Boyfriend and Sister too close?
Ok, so I have a great guy that we have a very good relationship (both are in our early 20's) and talk about everything about from one thing, apart from his relationship with his sister.
They are extremely close, luckily they aren't touchy with each other or anything weird. But they live together, just them, and when they are apart they are constantly texting each other. When I'm with him, its quite frequent that he'll say 'oh, I need to tell 'X' about this, she'll love it!'.
Me and her get on, but she is constantly there when I go round (and its me going to him more than not because it's easier; but when he comes to me he's constantly in contact with her.) It's making me feel very jealous and frustrated; then I feel angry because I shouldn't feel jealous of the sister?
They seem to have this connection, one that I perhaps feel that as the girlfriend I should have more, such as constant inside jokes and things that they have done. I end up feeling very much like the third wheel. Because she is single (with no interest of dating), whenever me and my boyfriend go out for a date, she's there too, such as the cinema, getting food, days out. There's no way I can say 'oh leave her alone at home, lets go just me and you' without being selfish.
Its obvious that he is trying to balance trying to please us both, but I seem to always come second. If me and the sister both want to watch a film at the cinema, he'll go with her over me, it feels like a competition at points that she constantly wins. We'll change our plans to suit the sister.
I really love my boyfriend, but I'm just not sure how much longer I can continue with this three-way relationship, its been going on now just over 2 years. I feel resentful and upset, but how can I bring this up with him? Please can anybody shed any light on if they have had a similar situation and the best way to face it?
