Why does he want to be the father of your children?

Answer

Case 1: You don't yet have children.
 Because he loves you. and wants to be a father.
 Of course he could be just pretending just to get you into bed.

Case 2: You already have children.
 Because he loves you and accepts your kids.
 Probability of pretence significantly lower.
 If your kids are below age 8 he may actually be
  more interested in being their father than being your husband.
