I've been having this issue recently where I have had the hardest time leaving my new boyfriend's place and thought I'd ask the boards if they'd felt anything similar. Maybe 4 months or so ago, I got out of a really awful relationship of 2 years and I've been dating this new guy for about a month. I'm completely head over heels and we've been spending a lot of time together.
The problem is that the past few times I've spent at his house, I've thrown a tantrum when it was time for me to leave. He hasn't asked me to leave abruptly or after we've had sex or anything that might justify a negative response and it's been after we've been hanging out together for 24-36 hours and it really is time for me to leave. Something about leaving triggers this completely negative response in me and it's taken hours of coaxing for me to eventually leave. The man has the patience of a saint and I'm so glad he's willing to work through it with me and not just call the cops or something, but it really needs to stop. I feel completely childish and needy when it's happened and I'm always painfully aware of how horribly I'm acting, but something about leaving makes me feel this sort of deep, painful emptiness that makes me want to die. It's intolerable. I've had a little of this happen previously with my ex when he tried to kick me out rather suddenly but I've never had this issue to this extent before.
I figure I'll find a way to apply some DBT techniques to the situation after I talk to my therapist, but I wanted to see if anyone had any advice or ever felt similarly.
