Should I stick around?

Okay so this is me and my ex. I met him my freshman year of highschool when I was with someone else. My bf at the time was super jealous of him so we didn't hang out much but once Scott and I broke up, nick and I started hanging out a lot more. Eventually we were together like every single day. We went to the movies and hung out at his house. We hung out at my house and had dinner with my parents and stuff. I thought maybe we could be something so I tried it. I wasn't over Scott so we ended it but we still hung out every single day. Well now I'm a junior and I realized like yo I'm in love with this dude. And he has always flirted with me and I knew he felt the same. But we had been in a couple fights before but we had made up and I didn't really think anything of it. So we start dating. I'm 16 and he's 18. My parents love him so they don't care that he's 18 and everything. Well apparently his parents found out and they don't like me because of past stuff that weve both gotten over. EVEN THOUGH HE IS 18 they took his car keys and his phone. So we stopped talking. I completely understand that just because he is graduated he needs to respect his parents and everything but it's not like I'm a shitty person or anything. But anyway, fair week we start hanging out and going around them and everything. About a month later, they see a pic of us on one of our friends snap stories. He lost his car and phone again supposedly. He still likes stuff in Facebook and reads my texts but doesn't answer. Idk if it's just his parents that are making him act that way or if I really just don't mean anything to him. I mean we've loved eachother for a very long time. How can we just be done? I dont know if I should just be done or if I should stick around to see if things change.

Update: one of his friends just told me he's talking to this girl named Alex which he told me not to worry about when we were together.
