Advice needed please?

My parents get mad at me every time cause they don't want me on my phone texting this guy that l used to sort of date/talk to. Like my phone always gets taken away and stuff every time they find out that I text him and I have no idea how to make it all stop. I have feelings for this guy because even though he's been rude to me sometimes he has also been nice to me a lot and I have great memories w him. Also I'm 22 almost 23 and I'm an adult.
I'm not even doing anything like on my phone or text messages that is wrong or anything. I'm always polite and respectful of peoples boundaries
