<human>: Backstory:

Me and H dated for 2 and a half years. We met in high school and started dating before my senior year. We had a great relationship for a year or so.

Around the year mark she started becoming unnecessarily angry. She went to the doctor and was diagnosed with severe bipolar disorder. She took pills for a month or two but stopped.

She moved in with me last June. Things were okay with small issues but we worked through it. The worst thing that happened was after an argument she threatened to stab me.

In December she tells me she has a crush on a coworker. We work through it and it goes okay.

In February she dumps me one day randomly and went to her Dads house. A few days later she came back.

About a week or two post coming back she leaves for good on the first of March.

I chased like an idiot. It's been about three months now and I was feeling okay.

My current dilemma:
She contacted me Monday. Wanting to fix us. We talked on the phone. A few things came out. She dated a guy for a couple of weeks. But things were over with him.

She seems to want me, but I'm scared to get hurt again. I asked her today if she really wanted me and her response was i don't know I want to take it slow and figure it out.

What do I do guys?
