I guess I'm confused.

I'm supposed to be polite, respectful, and positive, and simultaneously give no @#$^& about what she's doing?

It enrages me. She literally threw away our M so that she could go nuts and she's out randomly hooking up with guys FREQUENTLY.

Meanwhile, I'm alone, broke, and hurt ON TOP OF having a disorder that LITERALLY amplifies emotions.

And when I put my foot down about anything, she runs harder for the D. But if I don't, and I let her walk all over me, she wants ME to give up on her

Where's the balance? That's what I need help finding.
