My crush saw me flirting with another guy?

Long story short, I liked this guy (Christ). He's a player and flirt with everyone. I tried to move on. I flirt with him still but try not to have feelings. I have a crush on another guy (Jose). He knows I like him. I even asked him out, he said he would love to but he wants us to get to know each other a little more (we knew each other for 1 month by the time I asked). Yesterday Jose saw me and Christ flirting. I text Jose afterward asking how is he doing and he replied ":(" I asked him what's wrong then he ignores my text :/ Is he jealous what do I do now? We're not exclusively dating so I'm not cheating but he won't talk to me now I really like him what can I do?
