My boyf keeps hurting my feelings and I’ve decided to just distance myself, I have anxious attachment towards him, what should I do to be distant?

My boyfriend hides things from me to “stop a drama from happening” I always find out one way or another.
Yesterday when I was on call with him, his boss (without knowing I was on call) “jokingly” said my boyfriend was crushing on a girl. When I asked who he was referring to my boyfriend said that one of his campus friend has applied for a job at his workplace and he told the boss he knew her.

My question is why would anyone say you have a crush on someone just because you told them you knew them?

anyways my boyfriend said he used to like girls at campus before but not any more

I am having a roller coaster of emotions please give me your advice
