Still though I'd personally be a lot more comfortable/happy in Anna's position. She might not have the the ring yet but she's been dating and living with Tim for over two years (and it's perfectly normal not to be engaged by now). If/when it does come at least she'll know he made that decision to propose knowing full well what it's like to live with her and wanting that forever. They know what real life together is like. Unless one of Sam or Snez have secretly moved they still haven't experienced real life together yet. Not saying they won't work, but I don't think Anna has anything to be envious of either.
