<human>: Give me a shortened version of the text

Hello! This is my first time posting here, apologies for errors :)

I met my boyfriend Ben at college and we have been friends for nearly 2 years, dating for 6 months. during our first year of friendship, I was in a long distance relationship with Dave [20M] from high school, who was rather physically abusive and ended up cheating on me multiple times during our long distance. I broke it off with him when I found out, and haven't seen him for about a year.

My relationship with Ben is so different. He has many amazing qualities which I won't dive into, but most importantly he respects me as a person and loves me for my personality rather than for physical pleasure, which is something I never felt with Dave. Ben does know about my past with Dave and has supported me through my emotional breakdowns about it. 

Which brings me to now. Ben and I are on opposite sides of the planet over the summer, and currently I am back home. I was hanging out with my old high school group of friends when I finally saw Dave again. Seeing him again in a non-romantic perspective has given me the final closure I needed, and I feel like I have finally put everything in the past. I got the closure I needed in the "wow he really is a jerk, and it wasn't all just in my head" way rather than the "I had lingering feelings for him and now they are gone" way, if that makes any sense.

I mentioned this encounter and my "closure" thoughts to Ben, and he was very happy and supportive for me, but did mention how he was a little worried about the fact that I still needed this closure even when I was dating Ben. He told me he feels a little weird about it and understands that me completely moving forward now is great, but still isn't sure how he feels all of this.

How can I reassure him that I never had any feelings for Dave when I was dating Ben, that this closure doesn't affect my feelings for Ben, and that I'm moving in a forward direction with the past behind me?
