Thank you all so much for all the suggestions! To answer some of yours - the flats were mostly from foreign objects. One was a tiny piece of glass that was embedded in the tire and you could not see it from the outside or feel it on the inside (caused several flats). Another one was near the stem valve (not fixable). I have noticed excessive amounts of glass in the road, and there are so many thorns that I hate to take the bike off the pavement. Another one was from a goat head. I did have the LBS look at the tires, and they said the rear one was worn out and the front one almost worn out.
I do carry all the tools and tubes necessary to change a flat. But, so far, somebody else has helped me. When I did put on the new Gators, it was harder to get the last bit on the rim and my DH supervised the rear derailleur part. I'm just hoping that I won't have to change them so often. I usually fill my tires to 110psi and it was not a problem to inflate the Gators to that pressure. I also think the extra few ounces in the tires will not make that much difference compared to the extra weight on me. There's more weight in all those tools......
I also have some questions - TxDoc - what exactly are clinchers and tubulars? Bunny Ninja - could you please explain how to change a rear tire without taking the wheel off? It my head, it seems impossible.
Not all of my discomfort with riding alone is about changing flats (although mechanical things do not come easily to me). I did take a flat changing class and a bike maintenance class. My DH is an engineer and he can fix anything. Some fear is related to what if you have an accident and no one is there.
I try to ride with more than one friend. I am self employed and work is really slow now, so I have more time to ride. That's why I need to feel better about riding by myself.
