I don't think it's a problem , yeah your young and yeah he old but if you love him then why is that a problem, loads of people don't know what it feels like to fall in love with a very older person , if they were in that situation maybe they would understand.

I'm 15 and I'm really in love with a 23 year old man and I think he likes me back, just follow your heart, if you love him/her and he/her loves you don't let anything stop you being together xx
