Just live with it. Remember, I'm not Ken West. I.e. if a girlfriend is a guy's only focus then there's nothing for her to find interesting about the guy, and also it puts too much pressure on her and the relationship is likely to fail. There is security in bitterness or angst. Fear is what keeps us from ending it all.
Death is a great unknown.
Life is all about security. Even love is based in trust. A relationship is formed by trust and security. With a SO you can be sure that they will listen and care about what you say. That is security.
