MY SAD STORY - Despite the betrayal of my husband, I want to save the marriage

With such a problem as I have, I think, there were many women and everyone went through it in their own way. So I lived and never imagined that I would face this.

I'm married, have a child, lived with my husband, like all families - quarrels, life, we pay a mortgage, but when there is love, is it all okay? Like everything, as in ordinary families. But then she began to notice that her husband was worried about something and started drinking.

After some time, the reason for his behavior I saw in his phone. He communicated with the girl. They work together. Well, it started ... Talks, tears, mistrust. Several times they stopped their communication, then everything began again and now it has been almost a year. Recently my husband said that he loves her, but she will not live with her. She also has a family, husband and son.

Well, I'm confused, he does not quit his job, because there's a good income, I can not leave him, because I'm not completely dependent on him (my income is several times less). Such a dead end! I do not want to leave the family (as I understand it), until I tortured him with my jealousy, and I can not stop thinking about it. Every time I check his soc. network, find their correspondence and all in a circle.

Forgiven a few times. So now we decided to start everything from scratch, but how to stop cutting and torturing ourselves? How to start at least a little trust? Or is it just necessary to leave? And where to? How to raise a child alone? The future frightens me. I want to save the marriage!
