I also don't understand the laughing at the situation at all. You need to let him know that HE caused this situation and YOU will decide how it ends. Honestly. My husband had contact with a woman I didn't trust (for valid reasons and we both knew it - talked about it) and it caused a huge problem for us. I think his eyes opened when I got very real with him, honest. I told him our problem right then and there was his fault, his actions caused the fight and the extreme stress on our relationship. It was HIS problem to fix and I would let him know when it was fixed for me. It took YEARS.
I say you take Christy Lee's advice and serve him. Then he will know who is in control.
Also Suz T, take her advice too. Decide what YOU want and where you want to be in a week, month, year, decade. Do you see this man as a part of your plan? He wouldn't be in mine because I don't play those games...but if you want to play with him, go for it.
You got great advice here though, so I hope you take some of what we are telling you.
And I am one to support counseling, but until your husband is ready to take responsibility for his actions, nothing will happen no matter how many times you talk to a third party.
