Okay so I have a bit of a confusing situation and i really need advice. So, I started working at this bar a couple of months ago. I hit it off with one of my coworkers straight away and we began flirting a lot. Several people commented on it but I assumed nothing would ever happen due to the fact he is 7 years older than me. However, one night I was working and he wasn't but he was hanging out at the bar. He waited until I had finished my shift then he asked me if I wanted to go for a drink with him so I said yeah. He paid for all my drinks and we met some people he knew, one of whom commented on the fact that this guy seemed to have shaved and put on a nice shirt especially for me. Anyway, later on in the evening, my colleague kissed me. We were both a bit drunk but it felt great! He then took me back to his place and...well one thing lead to another. He kept saying how he wanted us to meet up again and when I said I had to go home, he kept trying to convince me to stay the night. Eventually, I did leave, and he even called me as I walked home to make sure I got back safe. I felt so happy and excited because I really like him and the whole night was so amazing and unexpected. But things were completely different the next day. He told me that he thought we should just be friends in order to keep things professional, which contradicted what he'd said the night before. Also, he's suddenly become very cool and distant, both in person and on social media. Also I have noticed he has suddenly started flirting with girls in front of me and stuff, almost as though he is trying to make me jealous? I have been playing it cool as I don't want him to see that I care but I feel very hurt and confused as I don't understand why he has Suddenly changed ! I know he gets a lot of female attention but it feels like he's purposely trying to make me feel jealous and like he's trying to make me chase him? I am confused because he initiated the kissing and everything else so why is he suddenly acting like he doesn't like me, when he clearly liked me enough to take me back to his place after pursuing me for a couple of months...does he like me and just trying to get a reaction or is he bad news? I need to know as I don't want to waste time on someone who's just going to mess me around. And what should I do? How should I act? I really need advice!
