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

[LIO]

I said hello this morning, tried to kiss his head (something he allowed several times this week before), and he asked about the paperwork. Then told me on Monday he will serve me.
So maddening. I'm probably pushing too much.

I asked for some money later today. I didn't want to, but two months of him not helping finanically, nor paying any money for kiddo is hurting a bit.

Advice needed:

Every night I sleep in our bed upstairs... Every night so far he sleeps downstairs. We own our home, but this was the year we were supposed to sell (we were on a 5 year plan to live here). We both hate the house.... So should I continue with my plan to fix and put the house up for sale this summer (with his permission), would that hurt the possibility of him coming back?

I have a tendency to rush things... He wants me to sell the home. I want to, but I also want a consistent place for s, and maybe for h to realize he should come back to... Yes I can afford it, but only if h is paying me c.s. It's tight.

I get the feeling that h is just regarding me as a formallity. Someone he can easily just go on ignoring indefinitely. Our schedules over the last 2 years lent themselves to that. It seems like he can just find a replacement activity or person for me, and focus all his energy into that instead of fixing anything with me. It's easier for him to "start over" with no strings.
Does anyone have experience with that? I'm struggling today emotionally...
