Need help with on again/off again Libra male - dumped by text message?

I'm sorry but he sounds extremely bipolar and in need of medication (not trying to be funny) And if this is the case he's doing you a favor by showing you exactly who he is now while you still have a chance to make a clean break and move onto to a healthy relationship. Go through your mourning period because 2 years is a long time to invest in someone. Keep all ties with him cut, don't even try to be his friend that will just make it worse. You sound like an smart girl, do the right thing for you. Good luck
