So i like this guy...

And he's really nice, we have a lot of fun together and he makes me happy. i believe he likes me back. but if he does i don't know if it would matter.
One of my best friends is a guy and he has liked me for the past year and has asked me out twice. i don't want to hurt him by going further with this other guy. I mean i did meet this other guy through my best friend. My best friend doesn't know i like this other guy and im afraid to tell him. what should i do?

Follow your heart, and yours only. Tell your best friend that you don't want to go any further in your relationship because you don't want it to be awkward, or that you don't want it to terminate if your relationship ends.

Talk to this other guy.
Whatevers meant to be will happen.

Yea that would be the route i WANT to take. but i really dont want to hurt my best friend. what if he stops talking to me over this. i know you may say (than he wasn't a good friend in the first place) but he's liked me for so long. and jelously could become a problem.

I can see what your saying, either way you will have to choose, which one you like more, im sure if you dont pick your best friend he will understand, i think he probly will get a bit jelous because he also loves you but he will also be happy for you if hes a proper friend.

Dont flaunt this new guy in his face. be courteous. but follow your heart.
