My marriage is a mess I've been married for 9yrs and we have 4 kids but over the last 3yrs things have been difficult my husband has cheated on me 2 times and I know I shouldn't have but I've taken him back because I loved him but this last time is different its as if he feels no matter what he does he thinks I'll just keep taking him back in but I made it very clear to him that I wan't I've got to a stage in my life I want more than what I've got and I now know I shouldn't have taken him back but at the same time don't want to hurt him like he hurt me but I've been having feelings about someone else this bloke nows I like him but I want cheat what do I do

First of all I think you two need to get into marriage counseling. He has cheated twice and now you want to cheat to get even with him? That will do nothing to make you feel better. If he refuses to go to counseling with you then you basically have only one choice left to you. Kick is worthless butt out.
