My ‘friend’ thinks she’s better than everyone. I have a confession.

I’ve got this ‘friend’ who thinks she’s better than everyone else. Armani Exchange jeans, a Dolce Gusto coffee machine, an Evoque on lease, a Michael Kors handbag, a nail salon in the spare room and, naturally, a grey crushed velvet sofa. You know, the full works. A full house in basic bitch bingo. Anyway, I slept with her fit husband on the aforementioned sofa and now I’m pregnant with his kid. What should I do?
