Perhaps we should do a small breakdown of my post. Allow me to re-iterate and expand upon the deeper meaning of my post.
"1- I can't be single in this game, 2- you can't be gay in this game. 3- Get over it."
"1- "I can't be single in this game"
This statement is used to convey a fact. The fact is that when I play Fallout 4 in it's un-modded form, my character is going to have to start out as being married, or in layman's terms, not single. When this statement is read in the context of this thread, and is used in conjunction with the rest of the sentence, the implication is one of personal disappointment, in the fact that I am unable to roleplay a character that is not (or has not been) in a relationship with someone in their own back story.
2- "you can't be gay in this game."
This statement also conveys a fact. The fact in this statement is that when you play Fallout 4 in it's unmodded form, your character will start the game in the position of being in a straight relationship, regardless of what you decide your characters personal orientation should be. In the context of this thread, this statement is used to show that I understand you are suffering a disappointment in regards to the opening scenes of the game. In the context of this sentence, this statement is used to show that I understand that we are both disappointed with the direction Bethesda has decided to take the opening scene of the game, even if we are both disappointed for different reasons.
3- "Get over it."
This final portion of the message while short, conveys a lot of meaning. In conjoining the first two parts of the sentence, the addition of these final three words imply that complaining about the situation in question will have little to no effect on the outcome. In this case, It will be the fact that when you start your game for the first time, your character will be in a hetrosixual relationship and simultaneously that when I start my game for the first time my character will be forced to be in a relationship(of any kind) as well. Finally, this last portion of the sentence requests that you do not complain fruitlessly about it, and simply accept your first Fallout 4 character's fate while waiting patiently for mods, while also implying that I should do the same.
