Some women expressed how they wouldn't want to propose to their guy because they want to know if they are serious about marriage. so they want the guy to do it. Sooo it makes me wonder if women even communicate they want marriage at some point before getting serious with the guy? Seems like important info to know before being heavily emotionally invested in him right?
You might try it this way "what are your views on marriage?" and hear his most honest unfiltered thoughts about it before proceeding any further.
Just a thought.
