Welcome to the club, I just went through this months ago

I just went through this last month. My story is similar to yours.
-Know for five, dated for three
-was pushing me through propose last year to a rough patch that led me to move away with just the clothes on my back
-she begged for us to get back together and I did
-We got back in August, every time we flew to see each other, we argued because she thought I was cheating on her, there was never another woman in the picture. She accused me of cheating with a female friend and read our messages , it became a huge blow up. Zero interest in dating this particular woman or even fukn her because I know she a nut case and know all her business.
-In february, I got accused again of cheating with multiple women, she blocked me on everything, mind you I am ready to buy a ring and propose( she was also pushing that shyt on me last year when I was about to ready to leave her ass).
-Despite how tempting it is to cheat long distance, I never got with another woman . Don't get me wrong, I am a man, I have thought about but I just couldn't do that to her
-Anyways, she dumped me, I left VA, she was suppose to come to ATL the next week. When I landed I realized I was blocked on everything. She texted my mom and dad that she discovered I cheated on her with multiple women. I don't know what it was. There was never another woman in the picture, I was extremely busy with work.
-After trying to get in touch, my boy and family talked some sense into me and I moved on

-I am enjoying the fuk out of this emotional peace I have
I told her I was hesitant about getting back together because I liked finally being in peace mode. I do think about her at times, I do miss her(not the arguing) Especially when I went back to our favorite city for work but no way I want to go back.
