I detached, he came back, but now it's BAD

My H only told me this past April the "I love you but I'm not in love with you" crap.

New Bulletin: Last week he had moved out and brought all his stuff to our son's place. After about 3 nights I get a text and after a number of hours of this I agreed to meet up with him. We had a good time all day; this was in Atlantic City and I was not staying there the night. Well he said at first he was staying but then said he wasn't. He then says he's coming home! After getting there I didn't say much, went to sleep and went to work the next day. When I got home all his stuff was there again and put away. So I'm thinking that maybe he's "seen the light" but its kind of the same attitude as last week. He's very to himself and not talking very much about anything. Its like we are just going on with our lives while he lives there.

So today is Day 3 of him being back and I mentioned that we have to talk after work or some time today. He acts like what are we going to talk about? I just want to know:

1. Is he home to work on things?
2. Is he back and trying to work things out with OW again? She's the one who threw him out.
3. Do I confront all of this or just use my DB skills and go about my life?

I don't feel comfortable just letting him be in the house that he was away from for 6 months. I'm afraid that he may be trying to get back with OW and that he's setting all of this up at my home. This is EXACTLY how it went down in April. I'm not going to be that stupid wife again who had no idea that this was going on until he said he was moving out. I know he wants me to initiate lovemaking and be a wife but I need to know that this is going somewhere positive. I don't want to nag either. Hellllppp
