opinion from guys...?

[michelle]

Ok I am currently seperated from my husband..he started cheating on me when I was pregnant...and has pretty much led a double life since then..I have found out that everything he has ever told me about his life was a complete lie..everything...well anyways the affair did not stop..we did get married and continued after as well...well I finally left him..and she moved into my home that day...which still upsets me..shows no respect for anyone not even herself..anyways..he tells me everyday how much he loves me and wants to be with me and how he screwed up...he wants me to move in with him at his new place and wants to try to have another child(he does not even help me take care of his son now..he claims he is always broke, but always has money for them???(meaning his mistress and him) but I know they are still together..and I am going into a deep depression over this because I truly love him...why would he do this? continue a relationship with both of us? any opinions or advice??
