Bestfriend and boyfriend issues?

For 4 years now (this started in 7th grade) my friend and i have liked/loved each other on and off. We dated in 7th grade for a day and then stopped but became best friends after that. 8th grade came and we liked each other back and forth, when i had a bf he liked me and when he had a gf i started liking him. That summer, he and his gf broke up and we had our first kiss during truth or dare. At that moment, he fell for me, but i was starting to like someone else and so on and so forth. We would hate each other, then love each other, but never at the same time. Now i have a boyfriend whom i plan to be with a while and he likes me again. We are both fed up with this and annoyed and need answers on why this keeps happening to us, can anyone help?! everyone always tells us how they think we are the perfect match too, which i think makes it worse for us.
