I hope you take this the right way. I mean to be helpful to you and to all the other men who write this same post with minor variations.

No girlfriend/wife/lover can fix your poor internal sense of self-worth. No external prop, be it a big income, big muscles, fame, or any other external false measure of self worth can fix your poor internal sense of self-worth. And it is unfair to ask (spoken or unspoken) any woman to be the prop to your sense of self-worth.

The absolute best thing you can do is explore with an expert (counselor, therapist, mental health professional, religious leader, guided men's group) how to find and get a grip on healthy self worth so that you can then go on to accept a girlfriend/lover/wife for the wonderful, unique individual she is with her own past and her own life before you came on the scene.

By doing this you can stop focusing on whether or not she ever touched some other man (or woman, for that matter). You'll also not have to worry constantly about the possibility that she will chase after some other man. Not because that possibility becomes totally impossible (that wouldn't be realistic) but because, having chosen a woman with good values, and having a strong sense of your own worth and a good grip on your own values, you will be ready to enter into a healthy relationship with a woman who shares your values and is willing to regard the past as the past and who is also interested in a healthy future with you (whether it be friendship, a love relationship, a marriage--the point is, it is mutual, with one person not having power over the other.

If I didn't think this was so important for people to understand, I wouldn't bother to post this. And if anyone thinks my post is inappropriate, please turn it in. I mean only to help. But it breaks my heart to see men (and women do it too) who cry over stuff that happened in the past when they are the person who chose who to connect with.

But what if your trust is broken? Deal with it if it happens and resolve to learn from it. I say it will still break down to: Getting and maintaining healthy self-esteem, and choosing a partner wisely (that means from the intelligence above the waist). Like I said, I hope this helps.
