Get a room ?

Sooo my ex of 18 years called a couple of weeks ago because he caught wind of the girl and I going out to SLC in January to visit my family.  He propositioned me that if he got a motel room if we could "hook up"? WTF??  I asked him to repeat himself, which he did enthusiastically and I proceeded to tell him NO !!  He got a little bent out of shape that I could answer so quickly and asked me to just take my time and think about it.  Again I thought about it for about 2 seconds and answered NO.  He said  "why not, we are familiar with each other".  Dear god !!!  I guess I could take it as a compliment, but NO that's ok.  And now I don't want to go out there at all.  Nice.
