Open relationship?

He doesn't want to talk about the status of our relationship (we made out a few times, but haven't had sex yet).

I get angry when he delays my questions. He knows exactly how to get on my nerves. Then laughs.

Yesterday joked about finally revealing the status being an "open relationship", to which I responded with a middle finger. And told him "so you are going to see others, huh?"... he replied "technically I'm meeting now with male friends only"... and cracked up. I got frustrated.

He then said "you have no other option but to accept that"

I feel numb. Why is he like that?
