Is it ok that I told my ex-gf of 3.5 years who dumped me that I’m not sure if I can be friends?

My girlfriend and I dated for 3.5 years, but she told me in April we needed to take space apart so I could get my life together if we were to have a future. I quickly checked into a rehab and she told me she was proud. I called her twice while there. It’s now September and I just found out via Instagram that she and this guy she met at our college graduation a year ago started dating while I was in treatment.

She met up with me twice after I got out and I loved showing her the personal progress I had made. My mental clarity was so much better and I got two jobs. But when I tried to ask her about us two months after I started treatment, she just acted confused and said “I didn’t realize I left things so unclear.”

A month later I texted her that I respected her decision to leave and thanked her for the relationship and she said it didn’t discount our friendship. She texted me a few days to wish me happy birthday and I told her I don’t know if we can be friends because things ended on really vague terms and we were together for a long time. She responded: “I guess I was just under a different impression but I understand.”

She never puts periods at the end of texts unless upset or angry. Can anyone offer any advice?
