Alone and pregnant

So I'm 15 weeks pregnant with my 2nd child. I am married with a 2 year old already. Well the other day my husband told me he doesn't want to be with me anymore and he sees me as a friend now. So he said he's going to go to therapy to see what the therapist says (basically saying that its up to therapist to say we should or shouldnt be together to make his final decision). Im totally heartbroken and don't know what to do. He said even if he decides to end it, he wont leave the house until baby is born and sleeping through the night. I'm so stressed out now and haven't been able to eat for days and have lost 5 lbs so far 😭😭😭 and what makes all of this worse, I wasn't sure I wanted another baby right now with how we have been, but he kept talking me into having another one right now even though I wasn't comfortable with it and now this is how he is treating me!!!

And he still is acting like he never said any of this to me. We still have sex, he still calls and texts me, etc.
