Re: after marriage
on the good side..what he may mean is that when you are married you have to make decisions keeping in mind they impact someone else, I felt that way when i got married and not in a bad way but some examples are i could not just be out and about at all hours or make a plan at the drop of a hat to go hang with friends in a different city for the weekend etc.
Otherwise, Not a good sign. I think you need to have one calm discussion where you must make sure that you dont get upset and try to find the answers to the questions, he may get upset and not answer them and getting into an argument is a great way to end a discussion. so find out what he means and make your decisions accordingly.
