when we moved in together four months ago, she explicitly said her dp comes round 3 nights a week - and she would like him to continue doing this in future (for various reasons she cant stay at his. We all agreed and were VERY accommodating about it.
As it is, he sleeps over more like 7 (i.e. most nights), spends most weekends at the house, cooks for them and takes showers here. I like him but he does not contribute to bills (her logic is that he is cooking for them both and she often offers round their cooking to us - thus negating the expense - and secondly that his showers are 2 minutes long...) She does all his washing too. He's getting a very good deal!! He earns about £800 less than me per month but his disposable income is far higher - and I often feel like I'm subsiding him!!
I like him, and them, and have put up with the situation for four months as it wasn'tbothering me too much. But things came to a head when he slept over/stayed round without her being there - showing that he clearly has moved in to all intents and purposes. Not only is this not ok (he doesn't do any chores, pay anything etc) but it wasn't what we originally agreed/was promised! And I don't want to share with a male and have to subsidise him. I do often feel like they treat the (very expensive) houseshare a bit like their own family house, and I am a lodger... Which riles me a bit as I'm paying exactly the same amount of rent...
How can I go about this conversation diplomatically and softly-softly? I really want a resolution and if poss an apology!
