Lol, I can not know what happened at last if he got married or not! But with 7 years and all the confidence that should have been, it is easier to propose marriage, surely she would know that you were going to propose it, women are very intelligent and advanced.
And in reality, it should appear and tell everyone what happened, in my case, it was easier, I just had to leave her pregnant to get married and a son is the best blessing for a couple, of course, if both want a child.
