Confused!

In the last two weeks my husband has run off for "alone" time and has left me with my daughter and this pregnancy. He came back home each time after a couple days to be back in love and saying sweet things and acting romantic. Tuesday he decided to tell me he only sees me as a friend and is not in love with me. A part of him wants to be with me and a part of him doesn't. He part that doesn't is stronger. He is not at home and has not seen our daughter since Tuesday morning. I even offered for him to see her this Sunday and he said it's too early. I'm an emotional roller coaster. He says he wants a divorce and that scares me. I am currently 6 months pregnant and feel so alone. Our daughter is almost four. Now he's saying he can't file right away because of money so he's gna give it time but wants space from everyone. Says he's unhappy with life in general. He told me he wants to be best friends. I'm so confused and hurt and pissed and I don't even know how to feel really. I'm hoping he misses me but he told me he hopes he doesn't miss me. And he's pretty sure he won't. He's not himself he would never hurt someone intentionally. I don't know what's going on!
