Bad ages?

Morgan
Okay so I don't know what to do. 
I've been talking to this guy for a year on and off.. He is 18, I am 15. When we started talking he was 17 and I was 14. We started off as friends first but then the relationship continued to grow. Is this wrong? I'm very concerned. Idk I just hope this isn't a problem because I do love him.❤️
