I'm not really sure I can give any good advice, but I just want to say that currently I am in a fairly unhealthy relationship, and both of us want friendship but I know it is not possible for me. Most of me wishes we never got to this stage, on the verge of ending it and losing each other completely (though neither are letting go). There are certain differences we didn't take into account that simply will not change. If you know it will never work out, then I don't think it's worth going through with it but at the same time I can understand how hard it is to bury feelings..

Perhaps both of you need some space to figure out how you feel? Either way, I guess open communication is best and obviously both of you have to be on the same page regardless of what you do.
