I wish I had some awesome advice for you but I can say that you’re definitely not alone. I’ve been with my bf for almost 8 months and there were many times I’ve said things I regret later. I think the reason it’s still going well is because he loves me no matter what and is very understanding about my mental illnesses. Does he know about your BPD and how it affects you?

youre very lucky my bf tells me to stop making excuses. I've told him 1957 called for their opinions back. He is very close minded about my mental illness

the thing that helps me is to notice the signs of when i'm starting to get very emotional and attempt to shut thise emotions down or at least conversation until i am thinking clearly
