Well, forget about the other guy first. He is making you feel something new again, like your husband did at the beginning with him. Now you are into the marriage and you are coming to terms with the fact that this is your life. So you have to decide if you want it to be your life or not.
My opinion, now that you have a child involved, you owe it to everyone, yourself included, to try to make things work. That doesn't mean they will, but you should try. You should go to couple's counseling with your husband. You have to work through the old pain and resentment and see where you can be together on things.
I am not saying it will work. First, BOTH you and your husband want to work to make it better. If one of you doesn't want to work on the marriage, it is just a matter of time before it is over. Secondly, though, some people are just not meant to be together. Sometimes people just have too many differences about the important things to them.
Get together with your husband and work on it.
