Having a rough day...

So my husband and I have been together for 9 years... About a year ago he said he wanted a divorce so instead of my usual (chasing after him) I decided fine you obviously made up your mind to leave me and our 4 kids. Well he moved out and I got involved with his friend (horrible I know I feel like shit about it too) well we decided to get back together and work it out...boy has it been a bumpy year for us.!! But I own it and really feel bad. Wel a couple weeks ago he went to the strip club and got 2 lap dances. This broke my heart, here we are trying to mend our marriage and he does that! I feel so ashamed of my body and so insecure. I know what I did is WAY worse but this really hurt me. Well he acts like its no big deal because I did what I did. I can't stop thinking about him in a strip club and they way I found out was because his shorts smelled strongly of perfume. What do I do???? What really bothers me is his lack of care that he hurt me. Please ladies give me some feed back!!!!
