Torn, torn, torn

I have been in a relationship with someone for about 6 months now. We knew each other when we were in middle school many years ago and were friends then. We both are coming from horrible long term marriages and are divorced now. When we first met we decided because of the past marital problems we would take things easy and slow and possibly have a FWB type of relationship. Its been pretty good til about a month ago. I have developed some deep feelings for her and I think she has for me but is afraid to show how she really feels. We have struggled some because of this. But this past week she told me about a text she got from a guy she met online. I have some good insight and knew she wasn't telling me the whole story. I ended up on her phone today looking to get online. Her email account suddenly popped up with emails between this guy and her. I know beyond a shadow of a doubt I should not have read them but my self preservation kicked in being in a past long term relationship that had a lot to do with infidelity. The gist of the emails were they plan on meeting next Monday for what looks like sex. See I have a ED problem that is getting better but have had some health issues the last few years but am getting healthier. I know with this FWB relationship that she really does not have a commitment to me but she knows how I feel about her. The emails hurt. I really like this person even to the point of love. But I am afraid if I tell her about the meeting she will no trust me. But how am I to trust her. I am really in a bind right now and don't know which way to go.

not gonna b easy though....why don't u talk about commitment and see how it goes....if she wants to b with u really, she may buy it...else, u know what it is!!

Yes,its not so easy... But,what i think is you better talk with her and let her know your feelings.Tell everything whatever you feel but dont lie. Hope than she would understand you..... God bless you.
