Gemini that truely loved a Scorpio

It always seems to be the Gemini thats the big flirt and cheater. However in my situation. My ex boyfriend scorpio was just that. He loved bars and whatever attention he could get. In the end I found out of multiple affairs he had on me. We lived together for 4 years. It was truely a nitemare. He is a completely miserable man to this day. He is with one of the women he met at the bar. He is still cheating on her. He is very deep and does not like to share his feelings. That is very much a scorpio trait. I was there for this scorpio man through thick and thin. I treated him like a king. He took this Gemini woman for granted.
