graannted i've never proposed to somebody, but arent you usually like 100% certain its going down and its just like a formality on the road to getting married when you ask the question lol
No.. In relationships there's never a 100% guarantee on anything. Somebody may want to marry the other person, while that other person isn't ready to enter 'that stage'.. Even if the relationship is 'serious'. If it was a 100% certainty, then no man would ever get nervous about proposing..
Say even the woman has already talked about wanting to get married and start a family, it doesn't mean she's ready right then to say yes or get knocked up.. It's just something she'd like in the future.
