I have been dating this married man for two years we just had a baby together every six months he is back and forth between me and his wife she harasses me he tells me that he does not have the money to get a divorce I just want to know how to get rid of him but still let him have realtionship with our baby or just deal with him through a lawyer because everytime I try to keep things profesional he use that to come back into my life

set up visiting meeting at a public place as far as him coming back into your life..
he cant do that unless you let him, stop letting him straddle the fence.
