<human>: Can you provide a brief overview of the text?

The person I'm living with thinks we should contiue to have monogamous sex even though we are broken up and neither of us sees ourselves together in the future.  I would like to not feel obligated to have sex with him any more and I instead sometimes feel angry at him, as he does to me, over minor social infractions.  I feel like we moved in together too soon and we share a studio apartment and our lease is up in 3 months.  I'm wondering if his request is reasonable and whether I should just stick it out and what I could do about it.
<bot>: Is it reasonable for the person I'm sharing a studio apartment with to ask that we continue to have monogamous sex, even though we are broken up?
