Just can’t get rid of my exes and what I am willing to do for free things [FMM]

So overall last Sunday night I’ve had sex with my recent ex boyfriend, let’s call him John (real names have been changed). then still on the same night I’ve met up with an old hook up of mine let’s call him M. with who I haven’t talked for 3 years now, however I have recently messaged him after a drunk night out and seeing on social media that he is single again. So with M. we started talking to each other again just catching up what we have been up to and stuff. We decided it would be nice to meet up again sometime to have a proper catch up. I told him I am quite busy but I would be free on Sunday night after going out for dinner with my ex, John.

So I’ve met up with my ex boyfriend for dinner and also to retrieve some of my personal belongings that he still had them on him after we’ve broken up. In fairness, after we broke up we’ve remained friends or more like friends with benefit which still works perfectly fine. So we went out for dinner we talked and stuff had a good time. After dinner I have kindly asked to pay for dinner simply because I am broke as I currently don’t have a job. He wasn’t really happy with me and he was suggesting that now I owe him for that.
