Sounds a bit harsh, i think the OP is looking for advice on how to deal with it. Saying accept it or walk away is not really adding to the conversation. My suggestion would be to start to talk to your friend about how you feel about his/her situation. Try and get an understanding of just how they are feeling. Dont just come into a conversation with all your advice ready to go because it will make your friend back off. Be prepared to spend sometime to get to understand the underlying causes behind his/her need to shut down and not live life. There are probably some deep seated fears and stresses which are causing him/her to be this way. Walking away and just turning a blind eye to them is not going to help anyone.
