Should I tell him?

So the guy is with now is incredible. I don’t know how I got so lucky. I’m so in love and I wouldn’t change it for anything.

My last relationship (before the one I’m in now) was 2 1/2 years ago and it took me almost a year and a half to get over it. It was a very emotionally abusive, slightly physically abusive. I got away from it and things are great, it’s my past.

So I was scrolling through my Facebook and one of my friends posted something about my ex’s best friend being emotionally and physically abusive. It triggered some memories for me and made me think more like.. my ex and his bestfriend are both like this and it’s awful. With it triggering some memories and thoughts it’s made me wonder if I should tell my current boyfriend. I’ve mentioned my ex to him a few times but ive only mentioned that’s he treated me line crap.

Should I just tell him the full story or just let it be the past. I feel like telling him would make him understand my insecurities more than he already does but I’m not sure if it’s a topic I should even bring up. He’s talked to me about how his ex was emotionally abusive towards him and how she messed him up for a while but I’ve never given him much info about my experience with my ex.

I love my boyfriend so so deeply and I feel like him knowing this would be a good thing but I don’t want to worry him. Ya know?

What would you ladies do?
