I can help you today.
I am sorry that you are having this issue with your boyfriend. I am not sure you are going to like the answer I am giving however you may need to hear it. If he has notintention of getting a divorce because it is "easier" this way then it is very possible that he is hoping for a reconciliation with his wife. I would not continue this relationship, you are going to get hurt. You are not being insecure and I am sure he is a very nice man, that has nothing to do with the fact that this very nice man is afraid, or not able to tell you that he isn't doing anything. He is using his Dad as an excuse. He isn't vested in your relationship. The only thing you can hope for is that after you break it off he realizes that he needs to move on, gets divorced and commits to you.
thankyou you really just confirmed what i was thinking
