Help meeeeeeeee

So I'm in a situation right now I don't know how to get out

. I'm dating my bf since a year he's 25 I'm 19 he lives in my house with my family and help us with rent... I've been thinking about breaking up with him since 6 months or more but everytime I don't do it cause I don't wanna regret it , I don't have any other friend but him ... I don't wanna be alone and I know is wrong cause he really care about me and I feel like I'm just making him waste his time, I tried to break up with him before but he would start crying and I can't really see him like that so I take everything back and act like nothing happen... we went from friend to dating and living together too fast ... so now I don't know what to do, I care a lot about him but also when he wants to have sex I don't really want to, I see him more as a best friend and anything else.. I feel like a bitch please somebody that understand leave a comment
