Hello! Boy do I know how you feel! I am currently happily married, but OMG does your situation ring a bell from my dating days! First of all, you should not feel bad at all about wanting to talk to your boyfriend about the status of your relationship. If he is not on the same page, then that is his loss, not yours!
Unfortunately men can get scared off sometimes when we women come on strong about marriage and babies, but if he is at the same point in life you are, he will come around. If he doesn't, then you should move on (I know it is much harder to do than to say!) and find someone with the same desires in life as you.
My advice is to just continue on with your life and make choices for yourself like where your career takes you, where you want to live, and what you do for fun...based on what YOU want and not what you think might make him happy. Too many women (and I am speaking from personal experience making many many mistakes) let their life progress based on what their partner wants...and they forget about their own needs.
If it is meant to be it won't be so hard to communicate and be on the same page. I'm not saying give up on him...just be kinder and truer to yourself. Nothing wrong with wanting to plan to have children and think about where you want to live.
