My nesting partner (29M) and I (29F) have recently decided to split up. No one did anything wrong, but he's realized his feelings towards me have changed and we want different things out of life, so even though he respects me and cares about me very much, there really isn't a way forward for our relationship.

The tricky part is that we still have another 5 months on our lease, and neither of us can afford to move out early. We've always had separate bedrooms and have been very good roommates to each other, but since we've decided to go our separate ways, there's been tension around my other partners coming over when he's at home. He gets along with all of my partners, and I started dating all of them before the breakup, but he's said it's too painful for him to be around when they're over and see me doing the couple-ey things we used to do with other people. He says it feels like he can't exist comfortably in his own home while watching my other relationships thrive.

So now he's given me a sort of ultimatum (he didn't call it that, but that's what it seems like): either we continue acting like a normal couple until the lease is up (having dinner, watching our shows, physical intimacy, etc.), or my partners are not welcome in the house. For context, we've tried something like this in the time since the breakup, and I struggled a bit to feel comfortable, specifically with physical intimacy. Since then, we've talked more about his feelings in the relationship and determined that I was more invested in it than he was, which for me was the nail in the coffin. I can't continue a relationship with someone who cares about me but isn't in love with me anymore.

So, I know resuming normal relationship activities would be painful for me, but I'm also bothered by the thought of not being able to have my other partners in my home for the next 5 months. To complicate things, one of my partners currently lives with their mother, so while I can visit them, spending the night is not an option. Plus, my long-distance partner is planning to visit this week, has been for a month now, and I currently don't know where to host them, since I just paid some other major bills and can't afford a hotel for 3 nights.

I understand where he's coming from, especially since he doesn't have any other partners, and I'm trying to be as fair and compassionate as possible, but it feels like I'm being leveraged. I don't want to resume our relationship knowing it would likely be detrimental to my well-being, but I don't want to hurt my other partners by cancelling plans and putting parts of our relationships on hold for 5 months. He says I'm not putting myself in his shoes or considering his feelings, but I'm really trying to do the right thing, here. Any ideas?
