I've been with my partner 6 years, engaged for 5 and I'm very close to his best friend, the only issue is he's too close to me, he becomes very jealous if my partner and I are alone together (we all live in the same house) he doesn't like me showing any affection for my partner even if it's just a cuddle, he's always around so we never get out alone time that we both desperately crave, we've had to go to the extremes of booking nights in hotels just to have some time together but even when I'm not around him he's always messaging me, I feel like he's obsessed.. It's really getting me down and I feel like I can't tell my partner because he'll think it's in my head where they are both such close friends... I honestly don't know what to do, any advice???
