Trigger post for me but will throw in my two cents worth.

Personally cheating in any way is wrong. If you don't want to be with your husband any longer than let him go.. maybe both of you will find true happiness somewhere else. On the flip side if you think that you want to stay with your husband, like Perna says, hug him... It takes two to create a loving relationship but someone needs to make the first step.
This guy you were seeing sounds like he id playing games... and in the end more than yourself will get hurt. Think of his family, your family and do what seems right xx
