Hurt and Denial

My husband and I have fallen out of love. We rarely have sex and emotionally disconnected. He travels a lot and I suspect that he's unfaithful to me. But I stick around because I have a little girl that wants the father to be in the picture. About a year ago I met someone and we hit it off very well. We fell in love and have a lot of fun together. He doesn't want to continue this love affair and wants to get married and have children.. I want to be with him too but don't want to end the marriage for my child's sake. So he ended it and we remain friends. I can't get over him, when I see him my heartaches because I am still very much in love with him. We still chat daily and hug and kiss occassionally. In my heart, I know its only a matter of time that he will move on. This man brought life to me for the past year. Now I feel so empty and hurt inside. Should I totally end our friendship to try to get over the pain or should I continue to be friends?
