Hello I am new to this and need some advise....

I have been dating this guy :-D for about two months now and I think he has Terrets, even though he has not told me yet. When we go out to eat he is fine, I think he controls it but when we are at his house and watching TV i noticed that his head jerks for about 5 seconds, it will stop and maybe about another minute it will jerk again. He also may flicker his tongue out real fast with the jerking but not all the time. So I try to move or do something to distract him and then he will stop and look to see if I saw him. He is 37 and such a wonderful, handsome, sweet compassionate man, but I am confused on what is happening and if I can deal with it in the long run. He will blurt out "yea yea yea yea" and we both will laugh, at first I thought it was something on TV, but the more I notice the things and reading this forum I am beginning to think he has TS. You can tell he trys to stop the head ticks, but it seems like when he does it get's worse and he will cross his legs and uncross them or wiggle a little to stop the jerking. He will take his finger and flicker his lips real fast, he taps his legs, he makes weird noises sometimes and I am like what is going on and we laugh it off. I am confused and I wish he would tell me so I can get a a better understanding on this. :'(

Can anyone tell me if I should ask him if he has TS or should I wait until he is comfortable enough to tell me... Please help!

Thanks and I wish you all the best! :-D
