Low self esteem ruined my relationship with my girlfriend.
I was with my girlfriend for 4 1/2 years. I'm 20 and she's 22. The last 2 years we have had unresolved issues. She said that she didn't know what she wanted and but she loved me. Even though we had problems we still talked about getting married and having kids. But my insecurities and low self esteem made me go through her phone and for the past 2 months.
Before we broke up I saw some really flirty texts messages with two guys and conversations with another guy that she knows I don't like because I know he loves her in the romantic way. So the incident that caused her to break up with me was that I needed a ride to pick me up from work so I called her and she wouldn't answer so I called again and still no answer. So then I get a text saying from her saying I went out to eat with my friend. I knew it was a guy because anytime she goes out with her friends or guy friends I know she says I went out with _____ and mentions their name. So I started freaking out and getting mad so I went to her house and asked her who she went out with and she mentioned the guys name that loves her and has feelings for her.
So she told me that that's why she didn't want to be with me because I'm a psycho and have self esteem issues. I do feel like I ruined this relationship and I don't want things to end like this. We were best friends and I know she really loves me and I admit my insecurities played a role with some of our problems. I don't know what to do. Please any advise will help. Thank you.
