I definitely don't think you should be rude. that wouldn't be good. you just need to be respectfully friendly with a certain distance and use your healthy boundaries.
I don't find it odd that he is putting his other kids first. right now baby can't really ask for him to drive her places, or whatever, and I'm sure his exw guilts him into doing those things and we've already talked about how she has a ton of control over him. plus, many guys just don't know how to be involved with infants and toddlers. they just don't always relate, although I've seen other men be great dads to the infants, but it's not the norm. it's the stereotype that the mom takes care of the babies and dad doesn't get much involved. I see that a lot. It is sad though, but it might be good for you right now, at least there is still a little consistency, that he doesn't disappear for 6 months and then come back, I've seen that too.
your doing good, continue with the journal and keep it safe.
