Haha I wouldn't say they're angels.
But tbh, my next girlfriend could be my potential wife. Somebody I'd make serious financial investments with, somebody I'd make compromises for and big life decisions with, somebody I could hopefully raise a child with.
She will always come before my 'bros'. Obviously it's about balance. But if it shifts towards spending more time with her, then so be it.
The sort of people I go for anyway are understanding and have their own lives too, so I'd never be whipped.
