Search Results: making girlfriend jealous

This guy Jake and I have worked together for 4 months. We are both awkward and VERY shy. He has NO experience with girls and has never had a girlfriend. He gives me mixed signals and flirts or doesn’t flirt. After a month of dealing with his BS I asked him (note he ran away and avoided talking to me direct 3 times prior to this) he very hesitantly rejected me and then instantly felt bad. I was upset and for whatever reason he was upset too. He briefly talked about it with my friend on Saturday and he said he felt really bad and he doesn’t even know himself if he actually meant what he said. Today we worked together and I avoided him like the plague (because I was still hurt) but he tried to get me to talk and was trying not to be awkward about it (which people were impressed he did it because he’s always awkward). I wouldn’t talk to him and would give him dirty looks and walk fast past him. He also saw me looking like I was about to cry and he looked like he felt really bad. There’s also a new guy at work and he was flirting with me but then stopped when Jake came into the picture and Jake looked very jealous about the new guy but the guy completely backed off with flirting with me. He also kept coming down and looking for me as he walked (I worked in a different area tonight). Jake was flirting with me because he was getting very close to me and making jokes and going oh yeah I think you need help with that in like a low tone with a grin while we were standing next to each other and Jake sat right next to me when that new guy was sitting across the table from us and Jake was taking my stuff and just being really flirty. I don’t get it And at one point tonight we were both so close and looking at each other like we were gonna kiss but then I stopped it and was like Jake aren’t you supposed to be in (his area) and he’s like maybe with a grin and I walked away and was like bye Jake. And. He’s like cya on Saturday on the way out and I’m like yep bye Jake lol

He's 28. My boyfriend of over a year went to some sort of car event that he organised with his friend (of course mostly for drinking), there weren't only guys there but whole families too. I was meant to be there but he didn't tell me about the total cost of staying over a few nights there, told me about it a week before and I couldn't afford it at so short notice so I didn't go..
I was making gay jokes about him and that guy for months as they seem to be extremely close together (although they don't live in the same country now, they still message each other all the time like every single minute of the day, he claims it's only "him and that guy" and jokingly is jealous of his girlfriend etc.) and my boyfriend seems to be amused when I make these jokes, never offended so I find it suspicious..
So going back about that event he went to - I knew they're going to sleep in one house together, but it turns out it was one room so I'm not sure if it's normal for guys to sleep in 1 room together? I feel weird now knowing that. What do you think?
