Homophobe becoming “gay”

So this time last year I have started a new job and met many new colleagues. (making a long story short). The one of them openly thought that I am just too much (gay), we even had few arguments after I acused him of being a homophobe. He was even kinda proud to be so against everything gay. Here we are talking about a die hard football fan, massively rough looking with many tattoos.
After few months and few drinks with colleagues, I realized he is actaully a very sweet and vulnerable man, and he kinda started to like me more. After my intense brainstorming that his female friend with benefits is not good enough for him, and after he dumped her, we started talking about men and women and what we want etc. Just a year ago that man thought talking about feelings is gay. Talking to me is gay. Being in my presence is gay. And gay is bad.
A month ago we kissed (was a joke to make friends laugh). I got invitation to join him and his 3 male friends and their 3 girlfriends on their monthly sail in the North Sea. I thought it was awkward so I said no. He told my manager (his friend) that lately he feels its pity hes not gay because he would have loved dating me. I keep noticing his stares at me and it always gets so uncomfortable. No talk about feelings and stuff is going on anymore. He keeps inviting me for drinks, getting drunk and showing me his VPL, telling me I should stop going after girly boys and try a real man. When I say: sure, your place, now? - he backs off. Today I made a jealousy scene when I asked him if he slept with a girl we both know. First he said he didn’t, he only let her sit on his bike and gave her a lift. I didn’t believe. I said: jeeez, with that horseface! He got mad, roared he didn’t and that I shouldn’t worry. I left office because my manager was on his way to see whats going on. When I opened the door to leave, I heard him whisper: I wanna f... you, thats what I’m gonna do.
And now I just can’t wrap my mind around everything thats happening. Can it really be true? Isn’t he “supposed to humilite gays when he gets home drunk after a football match”? He is still kinda hostile or not friendly to other gay colleagues. He doesn’t even say goodmorning to them, while at the same time he lets me hug him and rub my face against his beard. Whats the deal with this man? I don’t know how to behave anymore. Friendship is lost now and there is nothing else instead, yet there is so much of “something”.

p.s. From disliking him from the bottom of my soul, I came to think about him 24/7. 😞 But I think that’s pretty clear.
