Yesterday I received this comment:
"What if you're not married, but you've become emotionally attached to someone you know you're not going to marry? Is it possible to break the attachment without destroying the friendship with him and his family?"
My first question would be: Is he as emotionally attached to you, as you are to him?
If he is, then it may be a bit more difficult because of the expectations he and his family may have. The family may expect that you will be in his future and it may be hard to let that go.
He may need to know that you'd like to back away emotionally from him and it doesn't mean you don't want his friendship, it just means you don't want to be as emotionally connected to him. This can be said in a very graceful way.
If he is not emotionally attached, then a lot of the "breaking" will be on you. Letting go of your own expectations of the relationship and not being emotionally available to him.
Breaking the attachment will include not being around, not manipulating the situation to be with him or talk to him, and just backing away from the friendship. Keeping your thoughts and conversation in check to make sure you're not sharing too much emotionally.
Hope this helps!
