What is a "break"

Recently i've been feeling really distant with my boyfriend. He only has my friends and i as friends, all of which i introduced him to. I feel sometimes obligated to stay with him. When we discussed just things he said i "made him" fall in love with me, and told him i wasn't going away to school, only forty mins away, which is still the plan, but i want to feel like i can do what i want to do. I have a bit of a crush on this other guy which i am trying so hard to ignore but just everything right now, plus this crush makes me want to go on a break. So what is a break exactly? And how do i still go on a break when my bf will guilt me by saying i promised to want forever? Thank you so much, this is a 8 month relationship which i get isn't that long but it just feels like i've been with him for a very long time.
