<human>: Can you summarize the given text in a few sentences?

Like the title says, my SO and I are moving in together after 7 years of dating. We waited so long because we both wanted to do the college thing (party, live with our friends, do our own thing, etc) and not moving too fast. Ultimately we are both incredibly happy we did this, but now we're a week away from FINALLY living together. And I'm kind of freaking out.

I'm a little worried because for the last 4 years (since we've both been in college) my days have revolved around where I'm going to sleep (his place or mine), where/what am I going to eat for breakfast/lunch/dinner (with him or not, at my place or his, etc.), am I going to see him after work/class/whatever, etc. And a week from now those thoughts will be virtually gone. And for the entirety of our 7 year relationship we've been maintaining and interacting on a temporary basis. I'm awful at explaining my thoughts, but I'll try. If either of us is feeling sad/upset/moody/cranky and wanted to be left alone, we both had places we go be alone at. I'm fairly even tempered and don't stay upset long, but he is a little moody and once he is put into a bad mood he stays that way. Usually I would just tell him I love him and head back to my place. Now... we'll be sharing a place. And I have no clue how we'll adapt to these changes. 

Any insight or advice about adjusting to living together would be helpful. I do believe (read: hope) that there is a way to work through the changes that we will inevitably face in a positive and constructive that will make our relationship thrive. And please tell me if I am being ridiculous or over thinking things. That's my specialty.
<bot>: I'm finally moving in with my SO and would like advice on how to gracefully adapt to the inevitable changes that we will be facing.
