What is going on here... and what do I do?

[LIO]

Really both. Not hearing from him, and then if I do call, it's hit or miss on the interaction. Sometimes we hit it off, sometimes he cold and just self-involved.

I hate that we barely saw each other before- and it was so easy for him to leave, like it didn't matter. With my S out of town, we have no reason to even interact, and everything is in 'vacation-mode' without having to take care of S's needs, or switch off who has him. One more week of trying to not contact him. One more week before we get out of vacation mode. Not sure how interactions will go.
