Stacy:
I glad for you...love's great...
two months is a short time frame, though...Try for a more middle-of-the-road committment first...bear in mind, I don't know the whole situation, but if he does pop the ?, push for a long engagement...you'll then see any changes he may go through for that.
If he tries some sly way to get your ring size (notice any missing jewelry lately?) or has some intricately planned activity (picnic in this spot, this time, or a hockey game on THIS NIGHT) that's a sign.
Yay Stacy!
