Questions: Guy's Behavior

Sorry, I posted this question earlier but didn’t really put any context in it.

I have a crush on a coworker. We have a flirty relationship and we get on really well. We have been there for each other through difficult times. He has shown mild jealousy at times and is affectionate outside of work when we’ve had a few drinks. He was the one who organised my birthday presents and card (for my 30th)

Recently, on a night out, I admitted to him that I like him more than a friend. I asked him if he felt the same way and he kept saying “you’re a lovely person”. When I asked him to answer the question, he said “yes I do” and sounded annoyed.

He was hot and cold with me at work after that but things have gone back to normal. In fact, when I was on holiday, one of our coworkers asked if he misses me and he said straight away “it’s very quiet”

Today, we were just chatting and it was just the two of us. I said to him “well you clearly hate me a lot” to which he said “yes…. immensely”

I’ve heard guys say the opposite of what they really mean when teasing. Was this him saying that he likes me?
