Phoenix slowly rising

[T-boned]

I need some help here. Those of you who have visited may remember my sitch, but here's a quick synopsis followed by my question.

H has filed, we have signed a marriage settlement, the divorce is to be final in late August. H has OW (at least I think he still does). I have been dark for a while, only answering if first contacted. Or only initiating if it is a legal or bill matter. At marriage settlement signing (late April) I was devastated but tried not to show it until he tried to get me to hug him afterward. Told him I couldn't do that - walked away and have not seen him since. We have talked a couple times on the phone but I've tried to keep it to business. Haven't talked to him in two weeks. Been having a very difficult time since the signing - am going to therapy - have deep issues which are causing me to be a bit stuck, but working on it. In two weeks he will be leaving for Spain for a month.

Last night at 10pm I happened to look at my phone, saw I had a missed call at 8pm. Was my H. Voice mail said, "Just calling to say "Hi". I'll talk to you later." What the heck? Why is he calling just to say hi? I don't want to return the call because hearing his voice makes me lose it - the voice mail was bad enough.

I say stay dark. Don't return the call - he didn't ask me to. But I don't want to appear unfriendly. Yet, I think I should just let him call me if he really wants to 'talk.'

Am I right not to call?
