Why would a guy tell my best friend that he deeply regrets dumping me?

Anonymous

So I dated this guy, it was a perfect match really. The feelings were mutual on both sides & then one day he decided to dump me, because he met someone else.

I moved on & accepted the situation.

Some time he started liking my stories again, replying to them, calling me & trying to find ways to make conversation.

I ignored this too, because why would I give a guy that dumped me the time of the day?

So my best friend was at the same event as him & they started talking. He asked a lot of questions about me & confessed that he deeply regrets dumping me & that he’s really hurt.

Why would he tell that to my best friend, when he certainly knows that she will be telling me?

So turns out he had a phase where he regretted dumping me. Now he’s telling a good male friend of mine & his how he never really was interested & he was just manipulating me. Doesn’t make sense, because of other factors. But I’m over it & I will just take these facts as what they are. Because if someone can’t communicate their feelings openly and honestly to my face, there will never be a potential future. I’m glad he dumped me. Turns out he’s kind of insane (fr), so I dodged a bullet.
