<human>: I kinda just need a yay or nay on this, I'm stuck between guilt and logic. We were together 3 years. Broke up months ago, didn't speak since. I broke up because we clearly wanted different things in a relationship and I didn't love him anymore. Actually I didn't love him or desire him any the last year of our relationship, but was too low and stupid to break up with him. He never really got a chance to answer to my breakup speech, which I still feel bad for.

Today I got a message from him (he probably sent many, but I blocked him) on a social media, where he asked me to please talk to him. It was clear he wants me back. I do NOT want him back, nor do I have anything unsaid to him. I'm in a new relationship and I'm very happy. I do feel bad for ignoring his message though. He's a good person and I really want him to move on and be happy too. Honestly I thought he had, cause he always said he never talks to exes. It made me sad that he's clearly still hurting because of me, and I feel so bad for him. My boyfriend thinks I should just ignore him. Should I answer him? Should I feel guilty for not letting him speak his mind?

Can you give me the gist of the text in a nutshell?
<bot>: ex contacts me after months and wants to talk, I feel bad for him, but don't want him or have anything to say.
