If I had a wife, or a girlfriend, and she passed away, I'd be devastated. I wouldn't be interested in dating for quite some time, and I'm talking years. I'd have to imagine that we would've been together for quite some time, and something happened and she died. Being in love with her, madly and deeply so, I'd mourn her death for years, and I don't think anyone would make me feel whole again.
