This sounds very familiar. It actually sounds a lot like what I have been going through with my friend but I didn't really want to see it. He isn't talking to me at the moment but I've convinced myself that he is the one for me but then he is the first person I've really had feelings for in over 5 years but I know that it isn't the same for him. It might have been that way in the beginning but there was a decline and I think I wouldn't let myself see it but I know I played a part in it with my behavior. I wish it didn't to be so hard, but it seems like you know what is best for you in your situation so just try to stay strong and stick to your guns.
