Still in the talking stage for almost 3 years

Hey guys i need advice. I’ve been talking to this one guy for almost 3 years now. We’ve “broken up” 3 times but always ends up talking again. Our parents know about us but in his side they think we’re dating. He’s a pretty nice guy and we get along well, but his communication skills is pretty bad. He doesnt tell me if he feels sad or if he had any problems with my actions. If i ask, he just says its nothing. Now i always notice if he feels sad so im always stuck on having to guess if he wants me to talk to him about whatever his problem is or if he wants space. Another thing is that he’s a little controlling and gets jealous easily. He doesnt like it when i wear shorts, if my bra strap shows, or i wear something that he finds revealing. He also gets jealous of my friends. To be fair, i do have lots of male friends, but most of them are my relatives, and the others are family friends. Thing is, i really dont understand how he doesnt like it if i spend time with my male cousins while his friend group are all girls and he’s the only guy. I dont even get jealous and just leave him be. He’s also done things like playfully touching a girl (with consent) and hid it from me, fyi i only found out a few months after that incident to which he said he was very sorry and would not do it again. He’s also made a rvpe joke about a dead girl which that one pretty upset me and i got mad at him.

Lately I’ve been thinking about cutting him off bc i feel like im only wasting my time. At first, i only treated him like a friend cuz i knew not too act too much like we were dating. But i started acting like his gf when he treated me like one. I didnt mind but ive since opened my eyes ever since my friend told me she felt bad for me for staying in this “relationship” for years now.

A few days ago, i told him that i would like it if he would not get too close to me. I elaborated ofc that i meant he could still hold my arm and such, but if he could stop getting too close to me like always hugging me, holding my waist, touching my legs, because i felt like that was too much and we dont even have a label yet. I know gettjng a label isnt really a big deal, but my family is pretty conservative and my mom has told me that she’d prefer it if i would stop acting like his gf bc we werent dating. Now, after i told him about how i felt, he’s since acted pretty distant with me and is kind of ignoring my messages. I’m actually pretty frustrated now bc he’s always like this whenever i kind of confront him abt something. Can i just block this guy??????
