Problem is, we have a child together hes only 2, and when I want to see him she brings herself down with him and thus you can see where refusing to let her in is not as easy as it sounds. And we haven't been working for the past 1 1/2 years, shouting, argueing, point scoring its just getting stupid, pathetic and I am calling it here, or at least trying to! Your right, she is uber clingy and thats whats making this so [censored] difficult!
Your profile says your 22 years old, so I'm assuming she's roughly the same age. In your original post and title, you neglected to mention you have a child. You never stated what the shouting and the like was about, you've said nothing to indicate whether the problems were serious, irreconcilable problems that could not be solved by some counseling and effort to fix what's wrong or flaws you see and are attempting to bail out on instead of actually doing anything about them, you neglected to mention whether you did seek counseling or not, and therefore, I know next to nothing about the situation, but I'll try my best to state my opinion on what I do know and assume.
If she is as young as I'm guessing she is, if you really have been together for five years, and if you really do have a child with her, she has a right to be "clingy", in my opinion. A child isn't some trivial detail of modern life that can be forgotten, five years are a long time for anyone to commit to anyone else, especially at your age and with the child considered, and therefore her being "clingy" makes perfect sense. I wouldn't agree with the approach she's taking, but simply quitting because you have some problems isn't the best solution, in my opinion. I can't sugercoat this next statement, so here it is as bluntly as possible from the perspective of a father-hating teenager whose own parents didn't have a working relationship and whose father practically ran off (although I don't want to see him, anyway, but that's another issue) and started another family:
This is not a simple break-up situation, this is an event that will affect the development and life of your child, your responsibility, and will have a lasting impact on the rest of your child's life. I don't know the circumstances surrounding your specific problems, but if it can be fixed, you should see to it that effort is pushed towards being it fixed. The very fact that you acknowledged her only as some girlfriend and the fact that you did not mention your child in your original post or title implies, to me, your own immediate desires being the main factor behind your current desire to end this relationship. I can't say anything about the mother of your child (not some random girlfriend, the mother of YOUR CHILD) or really much about you as I don't know either of you, but the manner in which you phrased your original post and what you've said so far, otherwise, only suggest to me that this was some rash decision (on your part) that wasn't brought to the attention of your mother's child, wasn't thoroughly considered (as in you did not think of how to solve the problem and just impulsively made this decision without consideration of your child's future), and therefore isn't something I can just condone. Again, however, since I really don't know much about the whole situation, it's not something I can entirely condemn, either, but I'm going with my gut instinct for my reaction and my gut instinct tells me you're basically trying to impulsively run away from your problems instead of solving them.
Another thing that came to mind is that you don't seem to be married to her. You had a child with her, yet didn't seem to make any actual committments to her or your child (who, again, is your responsibility)? What were you planning when you did have the child, to live separate lives not legally recognized as being united by anyone? How did you fully plan to care for the child? Were/Are you taking into consideration what the child will think and ask about when he/she is old enough? This is a serious issue and I can't stress that point enough, but I just can't help but get this sense of impulsive action coming from your post. It really is none of my business, but since you've brought this matter to the forums in the form of a topic, I'd very much like to know the answer to these questions and I'd really like to see you address some of the finer points of this issue... otherwise we have little to go on.
I'd also like to point out that, based on the assumed age, time of relationship, and status (motherhood) of your "girlfriend" (You'll have to forgive me, but that term implies something not serious, to me, and this is very serious), she has a right to be "clingy" because of the reasons I've already stated. I actually feel bad for her. What's a single, young woman with a child considered in modern society? The answer is pretty much "damaged goods". To be so young and already cast out of the dating scene, in many eyes, by having a child must be a tough and frightening concept. That she seems to have devoted practically her entire advlt life, thus far, to be being with you and even having a child with you would automatically excuse the sense of being "clingy" that might be reviled by you, to some degree. I also feel sorry for the child. To grow up with only one parent at a time is not the same or as beneficial as growing up in a united household of two loving parents... period.
I'm not by any means saying you don't care for your child as I can tell you do, but I don't believe your accurately estimating the severity of what you've done, are currently doing, and are planning to do in how it pertains to your child. It's a life-altering decision you're making and I just don't feel as though you've actually given it some in-depth consideration. That's all I have to say... at least until someone else says something new or you clear some of details up, but I'm not judging you as I don't know you or know the predicament, but just in case, I had to type this simply because I have a suspicion that my assumptions are, at least partially, probable.
