I have been with my boyfriend for almost two years and we both came into the relationship with baggage from prior relationships. We have struggled over the issue of being introvert/extrovert and because my boyfriend is dyslexic and never had any kind of therapy to help him with his communication skills. Recently he has been going through a phase where he is feeling very much like he's stuck and not going anywhere with his life which increased his withdrawl from me and our fighting. I found out that he met a girl at work that he flirted with and then lied to me and went to a party she gave. I also recently found out that when he met her at his job she was applying for a position and they now work together.

My issue is first and foremost that he lied to me depsite knowing how painful that would be given that my last relationship ended with lies. My second issue is that even though he chose a safe flirtation (she has a boyfriend and she knows about me), he still felt the need to pursue that kind of attention behind my back and then lie to my face about it.

I have confronted him about the problem and he has told me that he is sorry and VERY disappointed in himself for hurting me. He has admitted that he needs mental health therapy and is taking steps to get started. He has told me he loves me and would like to work things out but is afraid I will never be able to trust him again or that he will fail at therapy and hurt me again.

I am trying to decide if I should stay and give him a chance should he continue to pursue therapy and work with me on our relationship. Or, am I not walking away when I should?
