-He's 10 years older than me.
-He's told me he's apparently not married, nor have had children before. I do not know why, but when he told me this after he asked if we could date exclusively, I got the vibe he was lying.
-Apparently lives with a sibling. Haven't met a friend/family member yet.
-When we spoke about our views on sex, he at one point said that he dislikes to have sex with a woman he's not emotionally/attracted to, because it's such a drain on him. This sort of reminded me of a marriage relationship, where at times one after a while doesn't feel attracted to the other (maybe).
-We haven't slept together yet. When he asked me when I would feel comfortable doing so, I told that I wouldn't want to interfere and come to his house, with his sister there. So he suggested a nice hotel.
-At first, he would take me to places that were at least 20 minutes drive away, and takes me to the movies a lot. I sort of questioned this, but he would say that he loves the place. Lately he's been taking me to places that are closer, and much busier.
-When we're out and having dinner, he will usually look around the room a lot (not sure if this is a sign of a controlling man or..)

This is reminiscent of a relationship a friend of mine was in with the same age gap. At 41, he had never been married or living with anyone, etc. I told her that she should be very suspicious, and that he might have a double life or something. In the end, I was wrong about the double life; it turned out the reason he was very single all that time was his epic temper. Still, my advice about suspicion was good advice and it'll probably be good for you, too.
Most Helpful Girl
Older - thinks he can fool you
Not married - WHO is when trolling for a mistress
Lives w/sibling - actually his SO/wife/other
Sex must include attraction - smoke screen
Sex timetable - fish or cut bait, other woman you
Outings - you are not to be seen, then reported back to SO
On the lookout - can't relax until joint is cased, doesn't want to be surprised by "reporters", at least w/o a story at the ready if he can't duck out first when one is spotted or he can approach them w/o you to head them off with a lie
Guess you'll have to meet the sister ASAP.
If she really IS the sister, then cultivating a friendship with her can eventually spill the beans where (& with whom) he REALLY lives
It easy to agree with your evidence but now I wonder why you allowed to build to such epic proportions... you must really love him?
