Coffee dates are good. They don't need to last more than an hour unless you're having a great time. The purpose of the first meeting is not really a "date", just a chance to meet and see if you are INTERESTED in a date. (Kind of like meeting someone at a party and chatting with them for a bit).
His past marriage history tells you pretty much all you need to know. Anyone who at this age still thinks that meeting and sleeping with someone on a first date and then marrying them a month later is a good way to pick a spouse, has some issues (probably a love addict). I could see being impulsive like that once, as a young person, but repeating it?)
And btw, I'm not knocking first date sex. Usually unwise, but I've done it and not always regretted it. But you have to understand that doesn't mean LOVE, just lust.
I wouldn't be too strict on your age restrictions. It's more important that the person be at a similar or compatible stage of life, and has similar values around what they want out of life. The 65 year old who is retired and wants you to hang out at the golf course with him all the time might not be a match. A 65 year old scientist who is enthusiastic about his work and is really fit and youthful might be a perfect match. Whereas a fifty year old guy who has a two year old with his ex-wife might not be compatible at all, unless you look forward to raising another small child.
