Is this behaviour with ex boyfriend odd to you?

We broke up a month ago,we are really close friends so we stayed that way. We arranged a stayover soon at my place to catch up and we plan on a beach walk,movie we both love and he promised me a back massage with massage oil perhaps.(I might be allergic to the oil) He loves to tease me and say what he would like to do to med he does it sometimes,especially when tipsy. He said it was fun and when I asked him why he was doing that he said it 'sexually frustrates and excites us both'. He still calls me pretty etc..we go to the gym together,and talk everyday/phone when we can..friends say this is weird.(the latter part in particular,the former doesnt happen that often,just sometimes).

He said he isnt looking at other girls right now as he doesnt want to but he has hit on a girl at the gym a while back...which contradicts this.

?

Don't entertain that lol

He wants the freedom of seeing other girls whilst having u on the side
