Setting Boundaries for MLC Alien H

[In Limbo]

The last week without the boys was shortly after bomb and I thought I was going to lose my mind. They are what keeps me busy. I don't have solid plans, but do plan to try some new classes at the Y, do some shopping for clothes that fit (woo-hoo), call some friends I've played phone tag with for a while, invite a neighbor out to lunch and maybe even go see a chick flick. Wish I had a girls night out planned. But with it being the first week of summer, a lot of people have other plans.

Question - one of H's complaints was that I never met him enough for lunch (he even mentioned it again last night talking about the past). Should I offer next week to meet him for lunch? Or would that be pursuing too much?

I get so tired of the negative comments about the past from H. Any advice on how to steer that toward the here and now? I validate and try to talk more about right now, but it seems like he wants to bring up the past so he has something to be ticked off about, like it helps him justify the things he's doing/feeling. Any advice other than validating for how to get them less focused on past and more focused on now?
