You made it clear from the outset @CheerBear that you didn't want to do the whole all in commitment thing and yet he hasn't kept to those boundaries. I think you are doing the right thing for you and your LF - it certainly can't continue on the way it has been and you do not need the emotional blackmail that he seems intent on handing out.
It is never easy ending any relationship - especially when there have been some lovely moments with him as a friend - but what he wants and what you need out of this scenario are very different. I can imagine there will be a lot of resistance from him but we are here to walk along with you. It can go one of two ways, in my opinion - he accepts this decision and moves on (the preferred scenario) or he becomes like a petulant child and pleads for you not to end it - if he does that however it will further cement in your own mind that you are doing the right thing. Standing right beside you here Hon 
I have had little contact from friend this week myself but I haven't instigated any either. I think much like you there are certain things that I can't get around and despite the fact that there are parts of him I really like thse tricky things do play on my mind. It was only ever meant to be a friendship from my end and I think he is sitting right there with me on that too now. I made it very clear that is all I wanted and we have taled about it being that all it is. Unlike your friend he is respecting those boundaries. We do have really good conversations when we have been able to get together. I know he is feeling a little like he has let me down not being able to visit me but I am honestly okay with it - I would much rather visit him - that way I can leave when I want to and I don't feel that fear that my safe place is being invaded at my own home. He did say the other day that he has become very fond of me so that was nice to hear - but with no expectations beyond the friendship - again nice to have that re-inforced.
