Search Results: the urge to look at guys

So I was at a club with a group of friends including a guy friend of mine that I was close too (but we never ever dated or slept together). So everyone spread out and did their own thing and this tall cute Asian guy approaches me saying I'm beautiful and asks me if I'm Rusisan. He was also feeling the urge to give me a kiss but I pased so we exchanged numbers and just hugged. We stayed in touch but I was busy with business meetings and working at a hair salon. So we texted each other but then he told me I took way too long then he blocks me off facebook and instagram and we don't talk or see eac other till a year and a half later by chance. Then he adds me back to facebook and we re-connect and he inboxes me to meet up.
He was pretty friendly and nice and we had a good date and we had chemistry and couldn't get off of each other. He trusted me enough to bring me back to his place where we had sex, but after our date was done he started teling me to go back to my guy friend and he's better looking than him and he had unfriended him from Facebook as well - that jealous he got. He was also advising me to continue my career wit hairstyling and wished me all the best and gave me advice.
He blocks me after I leave his place off of all social media. The sex was great and we got along so why did he cut me off? And why was he so jealous of my guy friend if he only wanted to have sex with me? And what did he mean when he said it wasn't a good idea to see me again?
