Input: My ex and I dated a long time (like 7 years) and then my ex broke up with me unexpectedly. I was upset during it but we remained friends after still.

Sometime later my ex wanted to get back with me but I didn't really want to, but being friends was ok, sometimes my ex would push boundaries a bit and I'd not stop them but overall it wasn't attention I wanted. I think I mostly remained friends because of how long we were together and felt like removing each other from our lives would be difficult and we liked being friends overall. 

Well sometime last year I got a new partner and my partner had me remove bad influences from my life that I desperately needed to do, one of who was my ex. I completely ghosted my ex and despite my ex trying to contact me asking what's wrong, am I okay, how they wanted to remain friends with me cause I'm important to them, I never did respond.

Sometimes I consider messaging the ex and explaining why I ghosted them, but at the same time it's been about a year since it all happened, been about 4 years since they've broken up with me. Should I just leave it in the past, given how long it's been? My ex has still tried to talk to me through family so I know they're not over it completely still. 

The main reason I cut them out is because they were emotionally abusive towards me at times though it was mostly because their mental health wasn't good and I was always willing to bend over backwards for them no matter what. There was one time when we were both drunk that they got physical towards me but nothing other than that incident aside from yelling at me and it always came down to it being my fault, gray area for who's it actually was. 

WIBTA if I contacted them again? I don't actually want to keep talking to them but everyone says ghosting is bad so it makes me feel worse knowing I did it to not just them, but others as well. Most of who I cut out were people my current partner said were manipulating me which is true, I was put in many uncomfortable situations that I didn't know exactly how to get out of and figured that's how life is for me and dealt with it rather than making it stop. 

Tldr, WIBTA if I contacted my ex to explain why I ghosted?
