OP here again.
Hagred--I have to say that is the best and most practical advice given here so far. Thanks!
Ok, I knew the question would be asked sooner or later LOL! No, he hasn't had a vasectomy but that's because I have been spayed. After a bout with uterine cancer I had a total hysterectomy years before I met him. He says that was one reason among many he was interested in me. Not the only one or the top one, but one among many.
Here's a shocker that I'm sure will stir up a lot of controversy: Are you sitting down? He has a daughter from his first marriage. He adores her and she adores him. She is 17 now but I hear from everyone that she was very well behaved as a child. He says it's completely different when you have a child of your own and the authority to do something about bad behavior. The story goes that his first DW already had a son when they married who has severe cerebral palsy. He says that's a completely different kind of child rearing and I'd have to agree though I don't have any direct experience. First DW wanted to try again for a "normal" child but he was against that. Unbeknownst to him she stopped taking birth control pills and was quickly pregnant with Mary Ann and yes, I agree, if he never wanted any he should have taken the bull by the horns so to speak and gotten a vasectomy years earlier but he didn't. Since her birth he's been a loving father and since their divorce he's never missed visitation or a child support payment and is quick to cough up whatever else she needs (like money for band trips to WDW!)
Anyway, I don't have any direct experience but I think that it's totally different when it's your own child and you have control and authority.
Oh, and just to set the record straight, Ian isn't a bad kid. He's sociable, smart and quite a charmer. He is, I agree, spoiled and in need of discipline but he's not a little terrorist. They laugh at his antics at home and so he thinks everyone finds them cute and funny, as does my sister. I'm afraid when kindergarten starts in a couple of weeks he's in for a rude awakening but that's a whole 'nother post!
