I love a co-worker and don't know what to do.

Well if it has only been 2 days I wouldn't sweat it. People do get busy or just stop talking so much. Hard to say for sure without knowing a ton of detail and then it is still a guess.

Looking back your original post. Is there any other reason you believe is might be gay?

Actually, I've sent a message now and we texted for a long time. There is no other reason for me to believe that he might be gay. Actually he's not gay. He's either bisexual or heterosexual. 
We talked and I've JUST learned that he's not transfobic, that also makes him not homophobic I suppose  Sooo... I really do not know what to do or to say as next step. I love him soooo much! I dont wanna make a bad thing to lose him.
