Let's start from the beginning, I'm 23 my wife is 21. In total we have been dating and married 2yrs. She it's my first gf/wife/sexual experience etc. We meet through Instagram... lol. And we started talking, come to find out she lived 5miles from me. So we talked for a few days then she told me she was married but was not happy and wanted to leave him but didn't have the courage too. So as we continued to talk we really started to like each other, after a week we started hanging out, after 2 weeks we started having sex, Once she finished school she finally left him and divorced him and got with me. After 8 months of dating we got married. Everything was good for awhile, then I started working second shift, we grew distant, didn't have those deep conversations like we used to, everything I said or did was a problem or wrong. Eventually I found out she was talking to some other guy, she admitted it and apologized and I did my best to move on, he was from out of state and they never meet or anything, just talked/flirted. To this day that still bothers me, I can't help that. But recently it's gotten worse, one minute she is happy abd in love with me, the next its "do this or I'm divorcing you" and its perfectly ok for her to do something and if I dint like it it's "get over it" If I wanted to do the same a week later she says "no you're not doing that so get over it, if you do it I'm leaving you" I've been pushed and pushed and pushed away and hurt so much idk what to do. I mean ive doesn't literally every single day and night of the past 2yrs with this girl. We have never spent a day apart. I have so many memories with her, both good and some bad. She's my first love/gf/wife, I still have feelings for her, I still love her but I'm not in love with her, I don't want to break her heart, I'm not that kind of person, I hate to see people hurt but idk if I can take it any longer. I told her the other day maybe we should separate abd she says she's never been so hurt in her life, said she wanted to die etc, but then hours later its "either we are doing this or I want a divorce" I need outside advice, please help.
