I have been with my girlfriend for 3 years now and we have had a lot of problems in the last year, due to her only having part time work and us both living with our parents. Last summer I even found out she had set up a profile on a dating website, but she said it was because we were so stressed out and unhappy but that nothing happened and she was only on there for a weekend. Anyway, a few months ago she got a really good job and we have moved in together and everything has been much better. However, the other day when I was sorting things I came across a couple of her diaries from years ago when she was in a 7 year relationship with someone, but the diaries were full of her talking about fancying other girls and wanting to get with them. I felt really shocked that she was in a relationship and talking this way about so many other girls and it made me really worried. Also, there was something about her fancying her now best friend who is straight, which really shocked me as well as they're really close and txt each other all the time. I know they're just friends but a part of me wonders whether if this girl was gay, would they be together? I know it was wrong of me to read the diaries but the last year has left me feeling insecure and what I read has made me feel worse. I spoke to my girlfriend about it and she said that when she was in a relationship with this other girl, she was young and she wasn't completely happy and that's why she wanted to sleep with other girls. She said that when she met me her life changed and what we have is completely different and she knows that I am the one. But she did go on a dating website last summer so she has obviously thought about cheating on me too?? Right now, I am concerned about the two matters - is she going to cheat on me like she did with her ex? And does she still have feelings for her best friend? Any advise would be very much appreciated as I really want to get things back on track but just feel shocked by what I have seen.
