Widower back in the game

I lost my wife ten years ago, and I want to get back in the game.

Yes, ten years is a long time. I've been on a few dates... blind dates arranged by friends, online dating, but not too successful. I am 52, but still young at heart.

A lady 10 years my senior in my office has shown signals of interest, but for some reason I am afraid to jump in.

Just reaching out to other guys, preferably widowers, who can share their experience. Thanks.
