<human>: Lately me and my girlfriend of a year have been having a rough time. She had a pregnancy scare, she is stressed about school and wasn't sure if she would be happier focusing on herself or not. She broke up with me and I being sad and wanting to be comforted texting an old friend of mine in which I used to have interest. I reminded this friend how I used to feel about them and that I'd like to hang out to be comforted, they agreed and said they used to feel the same. I told them I wouldn't be able to move on for a while and that I still love my girlfriend. 

However, my girlfriend decided she wanted to be back together the following day. I told this girl who was planning on seeing me that I could no longer see her that day and me and my girlfriend ended up going on a fun date. It was a great time but on the way back home, while my girlfriend had my phone in her hand she got a text from this girl and got curious as to what she was talking about. She saw this and got terribly upset, wondering why I wouldn't just ask her to comfort me. I told her that I tried but she wanted nothing to do with me at the time and that I was looking for something similar to her, to recreate the feel of cuddling with her in hopes that I could feel a little better. 
She went hysterical and started crying like crazy, I felt bad, she no longer trusts me and decided that the only was we can stay together is if she forces herself to care less. I know this will make her eventually break up with me. 
I decided to delete my Facebook and all my phones contacts so I do not do this again, I know I won't and I now hate myself for being disloyal even in the slightest way. My low self esteem and need for contact has ruined my relationship and I do not know what to do to regain the trust I once had. Any advice?

Could you distill the essence of the text into 1-3 sentences?
<bot>: my girlfriend saw my texts I sent to a girl while we were broken up and fighting and got really upset and thinks I do not care for her or love her, don't know how I could fix this
