Relationships?

Does anybody else feel like their BPD is 100x worse when they’re in a relationship? Like I’m fine when I’m single. But the minute I get In a relationship it all goes to hell. I get obsessive and jealous and I’ve even gotten violent. Had a 10 hour long therapy session because I got stranded at my therapists office and he let me talk to him the whole time. Learned a lot about myself yesterday.. Just wanna know if anyone else feels this way..?
