Confused

I met this guy at the beginning of the year and we hit it off immediately. I had never in my life clicked so automatically with anyone and I knew it was reciprocal. We had fun just by being together and we always wanted to be together. He made me meet his family and presented me to friends, it was honestly the most perfect relationship. I thought he was as interested in starting something as I was. But he never actually made any "moves" as in tried to kiss me or have sex or anything.

One night i asked him why and turns out he's gay (he says he's bi but more gay than straight). So even though I was very very disappointed I offered to back off. He said he didn't want us to stop seeing each other because he never had such chemistry with anyone in his life and did not want to lose me. Since he didn't want people to know I just told all my friends that he was interested in someone else.

So we started out hanging as friends and I had genuinely started to move on when he started to act weird: he hugs me a lot, finds reasons to hold my hand, invites me to weekends at the beach, bought me earrings "just because", or chocolate with strawberries " because he knows they're my favourite ", is always worried about how I'm feeling, keeps joking to everyone that we're getting married and brings up the topic very often. When we go out dancing I actually feel sexual tension between us. His friends and family either tell me he likes me or want him to be with me. Same goes for my friends. It's like he wants to me with me but is scared.

Anyway, bottom line is I am completely and utterly confused. He said he's not interested because he's gay but acts like a boyfriend towards me! He's even told me he's stopped looking for a boyfriend for himself. I want to know what is going on with him so I'd know how to react. I am stuck not knowing if I should feel love or friendship and this emotional yoyo-ing is wrecking my mind!!! I would never want to lose him because I've never felt like this so fast (or ever!) with anyone but I am starting to think that maybe it would be healthier? I am terrified of the heartbreak that will ensue.

So basically my question is: should I "break up" with him?
