What am I doing?

I don't know what's going on. I went on a date this past Friday with a man in our ward who is also a widower. His wife died of cancer. He's is a lot older than me. So I'm not really sure it was even a date. A couple of weeks ago at church I noticed him staring at me in Sunday school. But these days a lot of people stare at me at church. Then before sacrament he came and sat by me and talked. Then he called me twice to check up on me. So I just brushed it aside as him feeling a sense of care for me because he knew how I felt. But then he asked me if I'd like to go to dinner with him. I said yes. We had a good time. We talked openly about Dave and his wife and how they died and how hard it is coping without them. I felt at ease around him and he was a perfect gentleman. Yes we got weird looks. I told him I hadn't been to the temple since Dave passed away. He told me that I should go because it's been a great source of comfort to him to go. He then asked me if I'd like to go with him sometime. I said yes. Now I understand I am very vulnerable to the rebound thing that happens to everyone after they come out of a relationship. His wife has been gone for a year and a half. So he's on the rebound as well. But I still don't know for sure what his intentions even are. He is a very kind and good man as good as they come. His job pays very well and he's quite wealthy. So what am I doing? Am I thinking selfishness and money, someone to take care of me financially, medically, socially? Is he being a dirty old man chasing after a young woman? My daughters say I'm reading too much into it all and to just have fun for now. I don't know what I'm doing. I just wish Dave would tell me what to do. I was never a good decision maker. I'm afraid to make decisions, because my last big decision resulted in Dave taking his life. Yes I still blame myself, even though logic says otherwise. If I hadn't made that decision 9 years ago Dave would still be here even if for a little while longer, which I'd gladly take. I'd sacrifice anything to have had Dave here a little longer.
