I think people ask because a lot of ex's complain that "my ex won't speak to me" and what they mean is that my ex won't rehash our divorce or talk about my feelings or discuss my feelings on their current date and so forth...Just the other day a girlfriend was trying to convince me that her sister should take sister's ex to court since he didn't bring his new girlfriend over to meet sister before he introduced new gf to their children. *sigh* I think that it would be nice if they had the kind of relationship where he did that...if godforbid I ever find myself in a similar situation I will endevor to have that kind of relationship, but if it isn't to be it isn't to be.
How very troubling that your ex wasn't even willing to participate in medical care for his child. Does he exersize visitation? It seems that the very act of exersizing visitation creates so many issues that we can't avoid talking about- even if we wanted to! I mean there are socks left here and there and allergies to let each other know about and appointments that can't be missed and so forth!
Have you considered on of those websites where you can each post and not actually TALK? I am thinking if he is able to communicate via written word.
