Thanks for asking, lol. Nope, haven't asked her yet. Things were so tight money-wise before Christmas I couldn't afford a ring. After her mother suggested I may do so at Christmas, and then didn't, my gf and I discussed the whole matter a little more in-depth.
We decided to leave that until after we move in together later this year, as in her opinion "that's a big enough deal".
She's not against it or anything, but I can understand her not wanting to rush things, and I wouldn't want to overwhelm her with that sort of thing too quickly. So, for now that's been put on hold. It will happen, just not yet.
