She's moving out and says that it's permanent

[Heywyre]

Not going to give you any advice as to what to do - obviously I would be treating things differently.

As for the engagement ring ... I don't know about the laws in the USA but in Canada (and we both follow common law) if you are engaged (not married) it depends on who breaks off the engagement. If the gf does, she has to give back the ring, if the guy does she gets to keep it. However, in a marital situation, I am assuming the ring is hers to keep - that would be unless you can justify it somehow (i.e. family heirloom etc.) but even then the chances are pretty slim. Think about it, if the ring is maritial property, I guess her clothes, shoes, purses, make-up all are too right? Do you want her going through your underwear drawer deciding which ones she wants to take with her? Get real - the ring, in all due fairness, is the least of your worries and if this is what you are focusing on, then maybe I can see why she is wanting to leave - your priorities are screwed up!
