why should I do about this guy I like?

I have been talking to this guy I work with. We started talking after I got out of a break up. I was always friendly with him since we were coworkers and he is very very attractive that about 98% of the females all drool over him. I was very hesitant to start talking to another guy after my breakup since it had been recent but I took the chance even though I knew getting involved with a coworker was a risk. As time went by and we talked I wasn’t ready to jump into a relationship, I like him a lot but I don’t want to rush anything. We both had talked about taking things slow & seeing where it goes. He is sweet and does little things that are very gentlemen like. He passes by my office & always compliments me, tries to make me feel better, or just passes by to say hi. When we go out he always hold the door for me, unlocks & opens my car door, always holds my hand and pays for my stuff unless I offer to. Sometimes I feel him being distant with me. He won’t talk to me for days when he is off. He blows me off when we make plans too. The first time he had said that he has personal things going on so I let it go but after that he didn’t say much. He just let it go & continued on. Recently we had some drama happen at work that people made up rumors that he was leaving me for this female we work with.. she is also the hoe at out job. We had decided the day before to give eachother space. So when I heard the rumors I did not go up to him to talk about it since I felt embarrassed with everyone coming at me about this. I texted him that night upset assuming the rumors were true when it’s not like me to do that. I’m a person who likes to talk about things in person and ask instead of assume. He got upset me with but not cause of the rumors. He was upset that I did an immature thing that I don’t do. Since that day we haven’t talked or seen each other in person how we used to. The last thing we had talked about was that he needed space and I needed space too cause I felt hurt and confused. I’m not sure what i should do... im not ready to talk to him right now but i don’t want to be distant in fear that he might move on & I wont. I’m also afraid to move on and what if he doesn’t move on.

What should I do?
