Random, as long as you two have each other you'll be able to weather most any storm. This is coming from 16 years of hardship, strife, some real doozies of fights. You know, all the good stuff they call relationships and life and so on.
You're worried about becoming just another hetero couple. Want to know a secret? I'll let you in on it. Relationships, all of them, are made up of people. Skin and bone, flesh and blood people. Whatever you present to "the outside" and let them see, it doesn't matter beyond what importance you two give it. It's about what you two put into it. About how you two make it work.
I get that sexual identity plays a big part of who (the royal) you are. Being a white cis male, that statement is about as far as I can go, but if my time here had taught me nothing else, it's that. And I can see where losing the support would hurt. But you both are swho you've always been. Love each other and you'll find the support you'll need. Might look different than what you've had before. But it'll be there. And you can still be active in the LGBT community. You'll still be who you were.
That btw is the longest way I've found to say congratulations.
