New-scared and confused

[Pato2]

Hi all,
I need some help.
My husband of almost 16 years told me on 1/16 he wasn't happy and wanted a divorce. I was blindsided. We have been struggling for the past year, essentially living as roommates. We discovered in hindsight I was in a depression, not suicidal, but just getting by day to day. We didn't fight. we have s8 and d5 and lived for the kids.
I did an immediate 180. I had been digging myself out of the depression anyway and went into hyperspeed. I was happier, smiled, we went out socially, I talked to him everyday about job, hobbies, etc. (it is one sided though, he doesn't ask about mine, but talks openly about his stuff). I work FT, but do at least 1 hour of growth listening/reading/journaling each day. I see an IC and am working on GAL, but I pushed most friends away during the depression, so don't have that level of support right now or social life.
We were intimate on a number of occasions, about 1x week, that were mutual. Monday 4/18 we met with a MC and my husband said he would go again. He is mainly concerned about the kids. By Thursday 4/21 husband didn't know who this new person was/is. He is confused, feels he can't trust this new person in the long run, still unhappy, and last week said he still wants to move out--but he doesn't have anyplace to go.The sex is just sex, and there isn't a spark. I was an emotional mess during that conversation and didn't help things at all. However, as I laid crying on the bed, he came and spooned with me and held me while I cried. Didn't say a word, and left when I got it together.
We obviously still live together, he has been sleeping in the spare room most every night since the BD. Our kids truly are clueless, and in fact think things at home are "more fun" since we are doing more together. He has said the reason he stayed this long is because the "new" me is so pleasant and that is hard. The ups and downs are so hard.
I read Divorce Remedy twice in the past few days. I don't know if I continue on the "pursurer" path, initiating conversations, non-sexual touch, a friendly text during the day (to which he generally replies) since that has somewhat worked- or if I need to back off-and to what extent as he is still wanting to leave. I don't understand the "nowhere to go." Our funds are split (long story), we are fairly comfortable, with good jobs, with most equity in the house. So, he couldn't buy a house, but certainly could afford an apt, or live with his parents or brother in the short term.
We see MC again tomorrow. This [censored] as you all know. I have read most of the newcomer posts, and just need some support.
