How are you doing? And how do you feel you two are holding up together?
A relationship always changes when you become - or about to become - parents. It is inevitable. But like everything else, one should always talk, talk and talk some more about how you both feel to each other. The worst possible situation at this time is to keep things bottled up until they eventually explode. If you have always felt inadequate about opening up to each other, then this is an opportunity to improve on that front.
