<human>: Can you condense the text into three sentences or less?

My current boyfriend is the best boyfriend I've ever had. We love each other a lot and want to be together for a very long time. Our relationship is very wonderful. He is the only man to ever make me feel this way. 

My ex and I were together for 2 years. He suffered from PTSD from the military and became abusive at the end of our relationship and eventually broke up with me. I missed him a lot... Forward a few months... he messages me and says he still loves me and wants to try again. I then broke his heart. I told him that while I still felt a lot towards him, we needed to move on. He reluctantly agrees and we do not contact each other much more.

I started dating my current boyfriend ~1 month after this. I lose ALL romantic feeling for my ex before I started dating my boyfriend. A few days ago, my ex messaged me. We talked for a bit (with my current boyfriend's knowledge). He seems to be in a much better place in life. I know he started therapy shortly before he tried to rekindle the relationship, and it seems to have helped him a lot. He also got a stable post-military job and enrolled in college. A few days after this talk, he called me and told me that he still felt very strongly about me, but since there was 0 hope, he was working on moving on. He sort of poured his heart out to me, though... Talking about how he would lay awake at night and think of me, it's been very hard on him but he's trying to respect boundaries, etc.

I feel bad about this, but I actually worry a lot about him and feel bad that he is struggling so much with our breakup. He is a really good guy who went through a lot of trauma and I want him to be in a good place in life. Obviously, I feel like I can't be very helpful here since contact with me will worsen the situation. But it does lay heavily on my heart.

Does anyone have any advice for me/the situation? Thanks.
<bot>: I feel bad because my ex, who I am on good terms with, seems to have a lot of trouble getting over me. I do not have any romantic feelings toward him at all.
