Do you think this age gap is weird?

Long story short, I am not with him anymore as he was horribly abusive, and now I realize I was being taken advantage of, but do you think an age gap between a 13 year old and a 16-17 year old is weird? I want your opinions. Personally, I think it is very weird and I will defend and protect any of the people I knew in high school who are 13 from getting manipulated by a 17 year old. I just find it very wrong because those two age groups are in completely different life stages. One is just entering high school, one is getting ready to go off to college. It’s just wrong. My advice for any young girls on this app is that an older boy/girl who is interested in being with you is just looking to manipulate and toy with you: stay safe.
