I don’t know what to do?

I don’t actually understand how guys work they don’t make sense to me like if you don’t want me than just tell me that shit won’t hurt me I can take it but instead they don’t do that they plan a whole stage to lead us on… I know girls do it to guys as well… let’s take the guy I had a crush on for example.

He planned this whole entire let me love bomb her in that stage he would talk to me aloe follow me on other social media etc than one day out the blue he changed he just stopped bothering with me he decided to distant himself followed by using excuses to not wanna talk…. as I mentioned we got into an argument where I was jealous of his ex girlfriend but I guess he’d never caught the hint!!! And decided we are best off not pursuing anything mutual decision but a could have days later after he decided that. He slept with two different girls one no surprise was his crush!!! It’s like he’s teasing me when he told her about it to wind me up or something.

My world feels like it’s collapsed that’s just what it is he calls me to ask about money and sex so yeah ….. he seems to act like he has a future with her or something cause he spoke about her for 2 hours or so I dunno
