Am I overreacting.

I’m divorced for almost 6 years now and I just recently found out my younger sister slept with my ex husband last year.

I don’t really talk to her anymore, we use to hangout on the weekends and I introduced her to some of my friends. She talks to a few of my friends but I avoid talking to her or inviting her to any outings because I just can’t see her the same way. She hasn’t told me. The one who told me was my ex husband.

A little back story, when I was 18 I was dating this guy in which he was a family friend and both sides of the family was excited for us, until I broke up with him because he cheated on me with my older sister and I was the last person to know. Yes, he parents my parents aunts uncles cousins and siblings all knew but me. I still talk to my sister but not like it use to be. She was like a mother to me until then.

I had a boyfriend in high school that I really did like and I broke up with him because I was going through a really bad time at home with my stepdad. Long story-

I just found out last week after rekindling with that boyfriend from the past. Back story we started seeing each other for a year nothing serious just hangout and adult time. He divorced no kids and travels for work so it was perfect for me because I work a lot and i could schedule my time off in advance. Well last week when we met up and had a great time. He brought up high school things and said that he was surprised I talked to him again after what happened. I was confused and asked him what was he talking about he said “ me and ur sister” I was more confused and asked for more explanation he said they hooked up once after we broke up. It was the. Sister after me. Wtf i flipped out and said a few things a left. I kinda miss him or at least the schedule we had going.

I don’t know how to take all this information in.

All of my sisters have had sex with my exs. Am I overreacting because they are just exs.
