It's possible that despite all the red flags you've picked up, the fact that he wants you as much as he says he does, is enough of a reason for you to overlook all the potential dangers of this pairing. I mean, you're ignoring your gut instincts about him potentially being a predator. Don't predators kill their catch? It doesn't matter if he is or isn't. You're ignoring signs your body is telling you and that's a problem.. you're playing with fire.
You are important and deserve to find a person you feel safe with.. even a casual sexual encounter.. be safe. And you're right.. you're not responsible for his 63 years worth of "baggage".. and maybe you connected with him because of your own. Toxic feeds toxic.
He's good looking and sexy, ok. Is he worth it if you're only interested in a handful of encounters? If you're not as gullible as he thinks you are, you sure are giving him the torch.
If you have to be with him, find a nearby motel. Don't get lost (or trapped) on his farm.
