I don't have kids... it's a little hard for me to imagine how I might feel, if I did.

I think that, given you got his kids gifts (and the fact that he complained about his brother not getting them stuff) - yeah, he should have.

In general (if it weren't for that) - I'd probably be a bit more non-committal about it. My parents divorced just before I went to high school, and I don't remember their boyfriends/girlfriends ever getting me or my siblings anything. To be honest, they had a relationship with my parents, not with me, so I didn't expect or want anything from them (ha - except for them to go away!) It sounds like that might, maybe be different in your house though?

Is it possible that he's clueless about social stuff? That he just genuinely doesn't think/know about stuff like this? I only bring it up b/c some people are more "tuned in" to social standards. I'm usually *not*, but I've gotten better over the years (by messing up alot!) - and I'm female!
