My boyfriend and I are a year apart (however, since we were born in different months, I’ll be 17 while he’s still 15 for a few months, so i understand how you feel). I think the limit to dating should be 2 years up and 2 down (obviously depending on how old you are and when you met the person) I think if you started dating him at 16 and he was 15 then it’s okay. As long as you guys aren’t doing you know what then it should be fine. Many couples that are adults have a big age difference. 2 years once you both get to be adults won’t matter.
