GIRL!
Same thing over here... we knew we were going to get married "one day." We bought a house last year, we've been talking babies, etc.
Our moms got together and started talking about funding a DW so he and I said OKAY! and we have sent the STD, paid our deposits, gotten our passports, etc... but NO RING!!
he finally proposed this weekend but I totally feel you on the proposal story!
Don't worry, a ring doesn't symbolize the commitment unless the sentiment is there.
Be patient!
