So this has been an ongoing thing for about 3 years, I've spent so much time trying to decide if I'm justified or not. My gf complains about the smallest things, if I touch her foot getting out of bed, if I want the brighter lights on because I'm doing something but she wants the room darker(she generally likes a darker room and I'm the opposite), random people being assholes on the road. I used to be the same way and i spend a lot of time not saying anything to her because it always turns into an argument. I no longer let the small things bug me, if someone's following too close while I'm driving I move over and let them go that kind of stuff. I am 31 she is 24 and I try to be understanding that some things she just hasn't figured out yet but I also don't feel like I shouldn't have to just listen to a constant stream of complaint daily, I try to tell her that life would be a lot easier if she learned to let little things go but she doesn't take any criticism well so it's like my only choices are an argument or to STFU.
