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

When we met, he was married (which I know was a HUGE red flag, but I ignored it) with kids. We became romantically involved after about a year of knowing each other.

The relationship became long distance, and he moved to a crappy town to take a grueling (but high paying) job so that he could come and be with me within a year. He didn't file for divorce; he wanted to pay off his wife's debt (credit card abuse) and provide for his children. 

As we were apart for longer, I found that talking to him and spending time with him (almost exclusively texting) was more of a chore than a want. When we saw each other, I felt numb -- but I was unwilling to give him up.

Eventually, after nearly routine bouts of fighting, I called it off. He came to see me for one last weekend to say goodbye. I had so much fun with him, and I remembered all of the good times we had; I wanted him to stay with me. 

After he finally agreed late one night, I woke up the next morning and found that I was still left with a paralyzing doubt (was he really who I wanted to spend my life with? What if there was someone else? How could I introduce him -- age -- to my friends and colleagues?). I ended the relationship for good and he got onto a plane back to his family. That was yesterday.

He held me even when I was leaving him. I feel an inescapable guilt weighing on me. I feel that I ruined his life, and that I will never be able to be in a relationship without thinking of him.

Am I being naive? Will I move on? How can I make amends for having him move halfway across the country, only to send him back alone? What should I do?
<bot>: Post-breakup guilt. I feel that I ruined his life, and I don't know what to do about it.
