My girlfriend of 5 years isn't sure she wants to be with me anymore?
So I have been dating my girlfriend for 5 years we are 24 years old. She graduated college 2 years ago, I graduated last year. In November we purchased a house together (both of our names are on it). We are not married, nor engaged. A couple months ago things started going strangely between us. I could tell she was unhappy, but when I asked her if anything was wrong she would say no, or snap at me for asking more than once so I let it go, I figured it was better to let her figure it out rather than poke the bear. That was clearly the wrong decision on my part because I learned last month that she had been consoled by her male co-worker (40 years old).
I have no problem with her talking to co-workers about her life, it's expected as you spend 40+ hours a week with them, However from what I have learned the conversing went from casual talking to complaining about each other's significant other, to professing their love for each other. The only reason I know about this today is because a couple weeks ago I found a text message from him saying "I can't wait till we can just be together."
Following this I obviously got angry and we talked about it and she was blaming the whole situation on me because she thought I didn't love her. We talked that night and then the next day she was getting text messages from him saying he loved her and what not. Which of course set me off again because she didn't tell me everything the night before.
Now I thought everything was OK, until last night when she again went off on how she doesn't feel like I love her because we don't act like we did in the beginning of our relationship in the so called honeymoon stage.
I don't know how to deal with this because it seems there is no getting this out of her head. I don't want to brain wash her or change how she thinks, I just want her to be happy. On top of that we haven't had sex in 6 months and the frequency before that was about monthly. Another wrench thrown into this is the house. If we were to decide to go separate ways neither of us could afford to pay for it ourselves, Granted that is the last thing I want to think about.
Thank you for any input!
