Hello. I am 22 and have gone through the same things you are now. I know you feel bad because he loves you so much...but do what's best for you and actually him. That was the hardest thing for me, because what was best for him was not to be with me. I thought about cheating and pretty much hated him. We were never married but really that's a pretty easy fix. Do what makes you happy, soon, you don't want to waste the best years of your life!!
