Do Leo men keep coming back or is he really gone??

I'm a Virgo who was dating a Leo who was separated from his wife for 6 months when I met him in 2014. We dated and but mainly became really good friends because I'm divorced so I could understand what he was going through emotionally wise. About 8 months into the relationship he told me he loved me and I was shocked and thrilled. He started do things sexually he never did before and things were great. I met almost all his family and got close with his sister and mother. When he did things I didn't like I let him know that I wouldn't tolerate it and he would lose me. He didn't like when I did this and he would pull away for awhile saying I was mean or vindictive but would always text or call weeks later.
Well, things got worse and the arguing got bad because he detached from me emotionally and could never find time for me but could for his guy friends. I accused him of cheating and he always denied. I broke up with him, he begged for me back. He said I made making his head hurt with me questions, but I just wanted honesty. I'm a Virgo, that's how we are. Finally, we had a major blow up because I told his sister something he confided in me. He told me he would never trust me again to talk to about anything. I asked for forgiveness, but he wouldn't relent and a week later as I was leaving his mother's house I see him pull up with his wife. He said he's not back with her but that she lets him use her car.
I decided after arguing and things getting nasty that it was time to end it. I wrote his wife a message letting her know that he was with me for a year and a half and wishing them the best. He was pissed and said I went too far, but I felt like he could have been lying to both of us.
This may sound crazy but every time we fight we always end up contacting each other in some way. Even when we say were done he always texts for something and we start back up. So I guess what I nee to know is, do you think this is finally done? The message to the separated wife was meant to be a nail in the coffin because I knew if he tried to contact me I wouldn't have the will to walk away and he knows this. It was a deep cut but I felt I needed it to break free but I keep feeling like its not over which gives me hope but also scares me because it was nonstop arguing. Do Leoo men really love and try to reconnect versus finding something new? And how bad did I hurt him? I apologized but I was wrong.

Omg grow up

For his sake, I hope it is over. There are all kinds of wrong in the post. You need to grow up, gain self-confidence and learn what is means to be in a mature adult relationship.
