I need advice

I have this friend who I'm really close to but they don't care about me I've tried cutting them out of my life but I miss talking with them even though they can be a dick sometimes, I've always been there for them helping them through their problems but they have never really been there for me but yet I just feel so attached to them and I don't know how to cut them out of my life we've been close for about two years and I can't imagine a day where I don't yet them and yet we argue all the time usually everyone else that I don't get on with I cut out of my life but I can seem to bring myself to do it
