Well, my daughter (32) had been going out with this guy for 10 years so we just assumed that he would indeed pop the question. It just came out when he was here, he stepped into the kitchen said, "P and I were thinking of getting hitched, is that ok with you" and of course I said yes, only with pleasure. It was easy as that. Of course I know the guy quite well, we have all been on holiday together both here and overseas.
I presume you have made your intentions quite clear to your girl-friend? And she is as keen as you are?
