Strange situation

So in 2016 I was on Tinder, I was 16 at the time but my profile said 18. Anyway I matched with this guy and he was super nice and cute and I think he must’ve been 21-20 at the time but we would talk on sc sometimes. He didn’t know I was 16 as far as he knew I was 18. Fast forward to now 2020, I’m 20 and he’s 26 and I haven’t talked to him in 4 years and I haven’t be on tinder but I redownloaded it and we match again! He remembers me but doesn’t seem to realize that I’ve been the same age for 2 years or anything like that But wants to meet up. Do you think it’s be strange to meet up or no since I’m 20 now ?
