He's pushing your buttons with his odd humor and unpredictability. You're not used to moving in that way and are putting up some resistance.
You could say this to yourself:
"I'm asking myself to get over these things inside me so I can experience so much more with this man and within myself."
Try this the next time you feel funny, it's called "reality check"
"Y'know I'm feeling emotionally charged right now, could I ask you something to help me with how I feel?
I'm feeling when you do xyz you're doing it to upset me (or whatever your experience is). Is that true for you? "
And just let him answer.
