no seriously can it work out? genuine answers.

can a man, cheat, lie, be a drug addict and a waster and even carry every trait of a sociopath. cheat on his girl of 6 years whom he has 2 children to, get another women pregnant, leave her for this women, then get them BOTH pregnant at the same time, stick by the new women threwout the pregnancy not wanting to know the other one or be at the birth. then leave the new women when there second child is 7 months old and shes currently 4 montbs pregnant with there third baby. to run back to the first women of 6 years and live happily ever after with there 3 kids. not wanting to know his other 3 kids. can this relationship even work or be happy and loving? btw this isnt about me so dont start bashing on me. its about a friend who wont listen lol.
