Search Results: became more distant

I known this guy since middle school and now he and i are going to be seniors. I'm complete opposite of him. I'm very loud and energetic like a dog (like he said). He listens to everything i said and when i get jealous he would avoid the females i get jealous of. He would let me wear his shoes and basically annoy him. He always wait for me in my locker and classroom. When i talk dirty to him, he would say i feel uncomfortable or he will become awkward. When i tell him that i like a guy, he would be really distant until i told him im over that guy. His friends always make fun of him for hanging out with me while my friends claim he's my boy toy.

Okay, long story short, I've been in relationship with that guy for like... 6 months... but after a couple months, I started to have doubts on my feelings for him and I felt like a really bad person.. I didn't wanted him to be sad or mad at me, but I couldn't stop me from having these thoughts.. I became more distant and I asked myself if I should break up with him, even if he was a good guys and everything... I finally broke up with him, but after that, all my friends and his friends told me that I made a mistake and I would never find a man as good as him, and he was too good for me etc... Yesterday, my ex send me a message and told me that he's still in love with me..
I broke with him for a reason, and I'm pretty sure that I am not in love with him..
But what if my friends were right and I'm making a very big mistake?
What should I do?
