Sorry you're here, but you've come to the right place. Sounds like you've been doing well so far and you've got some good people checking in on you.
I think you're doing the right thing by not helping him find an apartment. It is his decision to leave so he needs to do it on his own.
I struggled a lot with trying to be friend-ly to my xBF but that was a different sitch with OW involved. In the end, I realized that trying to do what was best for him was directly at odds with trying to do what was best for me. Ultimately I had to put myself first because no one else would.
My suggestion would be to follow Puppy's advice to try to do what is right in every situation. What do you feel is the right thing to do?
Regarding sleep issues: I agree with others about getting some help with this. Like many others when the bomb was first dropped I lost 15-20 lbs that I didn't have to lose and my already existing sleep problems worsened significantly. I did go to my doctor and got prescriptions for both a sleep aid and an anti-depressant. I decided not to take the AD, but the sleeping pills have helped get me back on track.
