Just canvasing opinions here...partner of 10 years finally got round to proposing (also just about to have his baby). He's not one for grand romantic gestures and thats fine, plus he's hopelessly disorganised, but 2 months later an engagement ring has yet to appear. I don't really feel like it's official unless there's an (inexpensive) ring.
AIBU to start getting impatient? I sort of snapped the other day and said sod it, lets not bother if you lack this must enthusiasm...like I said, it's not about the monetary value.
