Four weeks in, hopeful but just starting!

bug - I don't know how to answer if we're S or not. I'm not sure if that's because I don't want to admit it, or if it is actually confusing. I don't feel like I understand what our status is. The facts are:
Dec. 15 - H tells me he doesn't want to be married anymore (doesn't say the D word), knows he'd be happier with someone else, etc. Over the next few weeks makes comments about how he thinks he can afford the house and wants to buy me out, that we'd have to split up the cell phone plan, a few other logistical things. I do the whole "I don't agree with this but accept it's your decision" thing and say he'll have to call a lawyer to figure it out, but that I think we can do a "do it yourself" or mediation w/ neutral lawyer since there's really nothing we need help settling.
January 2 - H admits to something w/ coworker (EA I guess?), says he feels closer to me after telling me the truth, but "it doesn't change anything"
January 13 - H tells me he'll call a lawyer "sometime this week" because he was "too busy" the previous week. I say OK, just let me know because I want us to be able to do this cooperatively if this is the route we are taking.
January 22 - I approach H about physical contact and am rejected with a "I don't think that's a good idea - nothing has changed"
Since then, zero references or mentions of D, the future, logistics, splitting finances, moving, etc. Occasionally he'll say things like "If you're going to X store, would you be able to get me this thing? I mean, I understand you don't have to, but..." that imply things are in fact different. But he still sits down to watch TV with me, eat dinner at the table (but not in his usual chair), goes to the grocery store with me, etc.

So, if H saying he doesn't want to be married means we're S, then I guess we are, despite living in the same house, watching TV together, etc.? I don't know, it's all very confusing and I guess is why it's hard for me know what's what because the signals seem very mixed.
