My WXW does the same thing. She went to Dallas during the summer for 3 days and didn't contact D4 once. When I've been away I've asked her to have D4 call me and on 2 different occasions she made up excuses as to why D4 couldn't call. First, was " she doesn't want to talk right now, I'll have her call you later" - she never did. 2nd "D4 went outside to play with her brothers"- several hours after I sent the txt request.
I contribute it to their self serving nature. There isn't anything we can do about it. Just keep being the best Dad's and Men we can be. Lead by example.
