...I'm 15 and I'm talking to a 19 year old, is this wrong?

I'm 15 years of age but I'm not like other girls my age...I have standards and beliefs for which I will always stand...for three years I've had a purity ring...so we won't be having sex...but I'm still uncertain in if this is right or wrong...I just need others opinions....feel free to rant and rave as much as you would like :) and thank you in advance
