What's going on with this dude?

There is nothing that says someone has to accept a "friends" request. Some people accept anything they get, some people are more choosy (I'm a "real friends only" type myself). That's their choice (in the same way that people have a choice to be friends in real life) and there is no point worrying about it. You just have to accept that, for some reason known to Tom and Tom alone, he is not interested in being friends on Facebook. And even if you knew why, it would not change anything - Tom would still not be your friend on Facebook. Our trying to guess his reasons is a waste of time

In any case, you said that you and Stacey hit it off and she's accepted your request. Surely that's the important thing?
