Have been going out with a woman (41) for about six months
She has invited her male friend over from Australia to stay with her for 2 weeks then they are going on holiday to Spain for a week
She has a 1 bedroom flat but she says he is sleeping in the front room
She also says it is a platonic friendship which I kind of believe
Anyway he arrived yesterday and I'm having a lot of trouble coping - I feel like I'm being disrespected and am a bit jealous as she doesn't actually go out (dates) with me much but is going out with him virtually every day
Any advice on how to cope (got a bit drunk last night :-( )
