My DS found me 15 months ago and called me. We talked sooo much. We talked on the phone about 3 times a week for several weeks (and we talked for hours each time) and also emailed. Then the calls became twice a week, and the emails from him stopped; then the calls became once a week (which was still great); and now it's every few weeks.

When I called him previously he would answer right away, or if not possible would call me back as soon as he could, but one of the last calls I made, he didn't call back for three days. The conversations seem to go fine. I have asked him before if I had done anything to upset him and he says everything is fine.

We have been together several times at my parents' house (a short drive from his home). I am going to visit my parents again soon and asked if he was planning to go over as he has done before and he was very non-committal (which makes me believe that there is something wrong as usually he immediately says yes).

I know that this may seem like nothing to worry about--it's not so much the frequency, as it is the change in freqency and consistency of contact; it's as though he's gradually pulling away. (DD says that maybe he feels smothered--but he was calling as much as I.) I don't want to make him feel obliged to talk to me. I don't know whether to keep calling or back off and wait--but then I worry that he may feel like I don't care about talking to him. I feel like I'm losing the closeness I had with him and I don't know why and it hurts.
