I would have to admit that S shows some serious warning signs about being a husband, but I wouldn't be ready to throw in the towel just yet.
A baby is on the way. A baby will thrive best in a loving hosuehold. The baby's arrival could have a positive impact on S in that nurturing and caring for his daughter could be the most important thing/woman in his life. In fact, I could see Jennifer becoming very jealous of the affection S lays on that girl if her needs are ignored.
S has had the ability to run away from any problem is his life. The day of reckoning, however, is coming with this baby and he will either have to grow up that day or continue wandering aimlessly (perhaps even happily) for the rest of his life.
And I have to add that no one, least of all me would have thought that my W would have an A and we would get divorced. I fell in love with W in no small measure because of her deep down commitment to family and against the modern "do as you will culture." Yet here I am.
This is why I mentioned earlier that I wish someone other than Jennifer could give S this speech on responsibility and being a man.
My concern is that S will never make a choice until he has to--and on this R front, that's not a good thing.
