What makes an ex want to get back together with someone and then decide not to be boyfriend and girlfriend with that someone later on?

I heard this from a friend of mine recently about their ex trying to get back together with the friend. The first time, which was quite a few months ago, the ex wanted to get back together with my friend and the ex ultimately decided they did not want to date the friend again. And recently the same ex is trying to get back together with my friend. Again. I personally suspect a pattern is going to merge for the ex being indecisive and not actually committing. But I'll give my friend's ex the benefit of the doubt.

Ultimately I'm curious about the psychology behind this and why people do this.

Likely, he is having a tough time getting laid or got dropped and the seven day "hold it-I'm going to die" thing has expired. Basically, he is probably wanting to move into friends with benefits.

For sex.

My friend is a male and his ex is a female. He set strict boundaries about not banging her until she showed that she was serious. I've already witnessed some red flags on her end regarding him but I'm not saying anything to him because while I care about his well-being, he needs to figure it out himself.

Thanks for the MHO!

I don’t know. Some people can’t seem to take NO for a answer and feel entitled to someone.
