My FP is my ex boyfriend and currently my best friend. Even though we broke up months ago, he says he's attracted to me again.

I'm obsessed with him, but he doesn't know.

And precisely because I'm obsessed, I avoid him and only talk to him through text messages. I fear I may get "too close" and hurt him or scare him away.

He's been asking why I avoid him, and I don't know what to tell him.

Should I talk to him about my bpd? I don't want to DIRECTLY tell him I have bpd, more like talk about some symptoms and about how I get obsessed with everyone I fall in love with.

I know people can take advantage of my bpd, but he's truly a great friend. Very understanding and caring. So I trust him more than anyone in the world.

What do you think?
