Can a baby change a guy?

Ladies, what do you think?

Do you believe a baby could really change a guy? My friend is pregnant by a guy she hasn’t known that long and now they’re dating and living at her parents house. He had an ex he dated for a long time (5 years) and was seeing her before he got my friend pregnant, but they weren’t dating. I believe he’s only with her for the baby but she thinks he’s in love and all. Let me just add that he recently got out of prison back in April. Do you think this baby will change their relationship for the better? I’m afraid that he’ll leave as soon as that baby is born.
