I have been married nearly 2 years and I still haven't gotten a formal proposal OR an engagement ring. My sister, matter-of-fact, bought our wedding bands, both didn't cost $100.00 total. I guess I was just one of them there dumber gold-diggers.
There are no *rules*. Everyone does what pleases THEM. Obviously is this dude didn't WANT to do this, then I don't think he would have.
