What do I do

So my ex and I have had a veryyyyy complicated relationship. We got together when we were young (16) and it was kinda toxic and rocky from there. Long story short we were just v immature. I overthought everythinggggggg and was really depressed and upset and we never had a normal relationship. It was always weird. Now is the third time we’ve broken up/started talking again (19). And we just saw each other again and it was amazing. We talked nonstop for hours and laughed and it was just an amazing afternoon, it was like being with my best friend again. Now I’m getting pressure from my parents to “talk to him about the relationship” and “make sure you’re setting boundaries this time” and “don’t let it get like it did previously”. And I know we’ll need to talk about it at some point, we have just a tiny bit, but I don’t know if I’m ready to really like... get there? And I understand what they’re saying because no matter what we really won’t ever be just friends (you know what I mean) but at the same time I just enjoy his company so much that I don’t want to jeopardize it.

I understand what my parents are saying, and I know I will need to talk to him soon if I want the relationship to go anywhere. But now I’m torn between telling him we really need to be just friends, which I don’t know if I can do, or talking to him about a relationship and risk it getting out of hand and becoming an emotional rollercoaster like it was previously.

We’ve obviously matured, but I really love him. Both romantically and platonically. He’s one of the most important people in my life, and I genuinely want him in my life. I just don’t know what to do
