Boyfriend issues....?

my boyfriend Ben and i have been going out for about a year now. i am 17, he is 16. I have been best friends with this guy Colin for about 2 ish years. Neither of them have ever liked eachother from the start. My boyfriend recently said to me that he doesnt want me to see Colin anymore. Don't worry, Colin has definately returned the favor of rudeness towards Ben. Ben has a very very tough living situation and we have been through too much to even start to describe. We love eachother more than we thought we would and i couldnt even imaging being with anybody else. I dont know what to do as far as a decision. Should i stay friends with Colin?
