I need ex-boyfriend advice?

So my ex-boyfriend and I went out for 3 years. We had a great time but there were times I felt like breaking up with him...well to be honest I just didn't really love him as much anymore...he's been a sweet guy to me and the best boyfriend anyone could ask for...i sound like a ***** for breaking up with him but i had to..i didnt want to lead him on...but anyways we broke up in May..it has been 3-4 months since the break up...we remained friends and it has been hard because I think of him only as a friend but he wants me back....I worry about him and I wish I didnt hurt him by breaking up with him but I had to. He is still having a hard time getting over the breakup..he tells me htat he misses me and thinks about me and he feels lonely with out me..im sick of it...i told him we can't be friends because he will not try to get over me...but he wnts to be my friend and Iwant to be his friend to because we still want to be apart of each others lives but not like a bf/gf. Ive told him that he is hurting himself by being friends with me because he still wants to talk and hang out. I told him that he shouldnt do that because he will never get over me then...I care about him a lot but as a friend. He told me that he would be devasted if we werent friends. I dnt mind being friends with him bc I dnt love him like that anymore. But he still wants to be my friend bc ithink he is trying to hold on to me still and he has this hope...I told him to get rid of that hope bc i dnt wnt to date him or anyone else right now..i lolve being single and I dnt think I am ready for a relationship after him bc i hurt him and I dnt wnt to hurt anyone else. I just need advice on how I can be friends with him. I have already decided not to call him that much maybe once a week or none...I just like to check up on him bc i care about him and wnat to make sure he is ok. I see him at college and I jsut say hey...We fought 2 days ago bc i tol dhim this friendship thing isnt working bc he stil lloves me and wants to be more than my friend...the next day we were both sad, especially him.,...i just worried about him,,,but later that night i called him and told him that it felt like another breakup...he was like yea. We just talked and i told him we can be friends but he really needs to try to get over me...i told him i wil always be there for him and help him...I also told him that i wnt call him as much anymore bc i want to give him some distance from me. he said that is fine but i can tell that he is sad about it. But he and I are both happy that we are trying to be friends instead of completely taking each other out of our lives bc that is too hard...I know the best I can do is reduce the contact i have with him..mahybe call him less and talk less to him online...I just hope he is able to move on and try to understand that what I am doing is best for him.
