Age gab

So There was a boy who lived in my neighborhood 4 years ago then he left the country and now lives in a very far city but we continued being friends, I was 11, he was 14 and but I didn’t think much of it because I thought it was okay, anyways we are still friends we did long distance relationship on and off throughout the 4 years, now I’m 15 and he’s 18 and he’s trying to get back to me and be together again but now that he crossed the legal age for dating do you think it’s okay if we get back together? I’m thinking of cutting him off of my life honestly💀💀💀
