Well, if he doesn't want to see you every day, then seeing them everyday, seems unrealistic.

Don't subject yourself to being his welcome mat, because he'll keep repeating the pattern with you.

He asked how you were. My coworkers ask that, old friends and new friends ask that.

How about a set visitation schedule, not one at his convenience without you being at his beck and call? Can he pick them up, at a halfway point? Do you have friends that can do the exchanges for you?

Doesn't seem healthy for you to see him like this. Can you block his fb?
