Guys, why do some guys rebound after a break-up?

I'm not saying all men are the same but I'm trying to understand what is the point of having a rebound girlfriend if she just ends up getting hurt? I speak from experience, I was unknowingly a rebound girlfriend. My ex told me that he really liked me and wanted to have meaningful relationship. But we only saw each other whenever he felt like it. He broke up with me because I got angry at him. I got angry because we didn't see each other for a week and he cancelled 2 dates on me but he insisted he really wanted to see me. That's not why I got angry, I was sad at first that we'd hadn't seen each other but then he sent me multiple texts saying he was moving away and never coming back and he knew about it the whole time. I asked twice if it was a joke and he said no. So, I got angry and cussed him out. I felt bad so I left a voicemail asking to talk it out. He called me back and said he wasn't going anywhere that it was just a joke. He said because I got angry that I scared him and he wanted to break up with me. He said the whole purpose of going out with me was because I reminded him of his ex of 2 years, I looked and kissed like her. She had just broke up with him one month before he asked me out. He insists that he really did want a relationship with me but also he just wanted to get over his ex faster. I was devastated and angry. He was my first boyfriend and everything. I never had a boyfriend before and was sad that I ended up getting hurt. After we broke up, we saw each other at work about 3 times. He just smiled and waved. I didn't acknowledge, just kept walking. Honestly, I feel a little better that the last time I saw him he got fatter and his face dark and bloated.
Why rebound? Do guys even feel bad about it?
