Is NOBODY wrong in the post ? POST : The first thing: I don't speak english very well, so sorry about any mistakes.

I was with my ex for three years, and honestly cared for him. We didn't live together, but spent a lot of time with each other. I dumped him a year ago, cause he was full of BS - he didn't want to work, and lacked ambition. All the time he was talking and annoying me with some business project he does, and told me he is actually unable to move forward without finishing it, since he planned to be rich. I got pretty sick of the bs.

Breakup went well, he even told me he gets my feelings, and wanted to stay friends. I said sure, why not - we live in quite small town and will run to each other quite often. Soon after, I've found someone else to date (we broke up already).
Half year after breakup, I've his project was finished - he managed to buy some expensive stuff - house, few fancy cars, speedboat, jewelry, whatever.

He called me and told me that I helped him a lot before, and If I need something, I can call him.

We went for dinner, while I had no any interest to be together again - and I told him on the spot - he responded he neither.
After that dinner, he and my female friend started to date - he buys her fancy clothes, takes her to vacations, pays for her manicures, sauna, pretty much everything he promised me for years - I think he does it on purpose to make me mad and jealous.

I know that I broke up with him, but still I feel like it's not fair when she gets lifestyle which supposed to be mine.
I was the one who stayed with him while no other woman would.

I know it's his money, and I don't feel entitled to it, yet, AITA for being mad at him?
