even if you broke up with him yesterday, that would've meant you guys started dating at 15! high-school and earlier relationships seriously do not count as real relationships!
We started dating 2/28 when I was 14, I had my 15th birthday during the first 6 months of our relationship. He was 17 at the time that we got together. It was the whole freshman dating a senior deal.
Somehow, age or not, I think 4 1/2 years counts as a real relationship.
i guess, maybe! probably more real for you than for him! (because girls are much more mature, i mean, and likelier to have a more serious, more real relationship earlier than guys. even 17 year old guys. named Weazal).
