Our time alone is coming to an end...

Which is exciting and scary, nervewrecking and thrilling all at once.  I can't wait till I'm able to hold my baby boys, but I know, realistically that things are going to be chaos and that my relationship is going to change. I'm trying to appreciate every minute I have alone with my husband (and my dog).  But I've received some unsolicited advice that both scared and humbled me.  My relationship is going to change, things are about to get hard and possibly push us apart further than we've ever been pushed.  I realize that our time alone will soon have to be paid for.  So I'm asking you experienced mommies for some advice... How do we go into it and come out the other end stronger? What can we do now to be as prepared as possible for when the babies come. How do we manage to remain close when we have two little babies literally between us? How do I help my husband and I still make sure we keep our relationship a priority without forgetting about each other? I'm not gonna lie I'm scared of change, I've never been one to welcome it.  My husband and I have been together since we were kids, 15 years now and this is going to rock our worlds, for the better I know this. I'm just trying to plan ahead so that we go into it knowing that we will come out on top together.  Ladies please be kind. I'm 7 months pregnant, I have two babies that sit on my lungs and I cry like every 5 seconds, I'm an emotionional bat case.  Thanks in advance for the help.
