Really confused, OP.
You say he initiated contact 11 weeks ago. I make that around 1 November. Yet you were on MN on 7 November saying you were going to divorce your husband and were having an EA with this man and had already exchanged a few "I love yous".
On that same thread you said this:
*Now you're making me doubt myself (which I guess is the point of these threads). I remember when we kissed I got the hunch he was a serial cheater, so maybe , that's who he really is? What do they get out of romancing? originally I just wanted some fun on the side...
You even say that although you aren't friends with his wife you know her and are friendly to her!
I know you were in an unhappy marriage. You say he is verbally abusive but you also said you were aware from the start you shouldn't have married him but you did, and you went on to have a child and decided to work at the marriage anyway.
I don't know what your mental health issues are but I suspect they are considerable and you're clearly not telling the full truth on your threads.
I urge you to step away from MN, step away from this other man, leave your husband, work on your self esteem and MH with your counsellor (I suggest getting a new one, as I'm not sure this one is doing you much good), consult your GP about your medication and then and only then, when you are in a good and proper place, look at any sort of relationship.
