I've been with my boyfriend on and off for ages, and have always trusted him 100% not to cheat etc, but something is getting to me at the moment. He's generally really quite shy around girls, but since he's started uni his best friends are his corridor, who are a mainly female group. Now they seem like nice girls (I've met them once but not properly, which doesn't help my worries) but they are really touchy feely and flirtatious with each other. They'll always be hugging and calling each other sexy and generally just going on about how fit my boyfriend is. We weren't together for most of this year at uni, so while I was jealous I knew it wasn't for me to say anything, but I did build up this kind of paranoia about it.
I feel like I don't have a right to say anything...most of the girls have long term boyfriends so I don't think they actually want my boyfriend, but I just don't like the way they are sooo all over each other! Now we're at home and back together it's still kind of annoying, they'll text/email/facebook him saying "hey sexy, missing your hotness soo much can't wait to see you xxxxxxx" and he'll respond in the same kind of way. Even friends have pointed out what a 'stud' he's become.
I have told him it's bothering me but he says it's just a kind of running joke and it's fine. Do I have a right to ask him to stop being like that? I really don't want to mess up their relationship, and it's not that I'm scared of anything happening between them at all cos I'm sure they're only messing but...arrghh!
