do we or don't we?

we have a playdate/sleepover scheduled for jackson tonight. the playdate this afternoon is with paul's cousin and her two boys, who we love and adore. the sleepover will be at paul's aunt's house tonight so that jackson can have a crib instead of a pack-n-play. they are totally doing us a solid by taking jackson, and we are so appreciative. we are having the rest of our belongings from storage delivered this afternoon, and having the uninterrupted time to complete our move will be so helpful (not to mention that this means paul and i can have an evening as adults.)
earlier this week, i posted about wanting a life, needing a sitter, and wanting to coexist as a mother and "woman of the world," as my grandmother would say. my opportunity to do this is today... tonight... and now i'm scared.
i'm not scared at all for jackson, nor is paul. his cousin and aunt are MORE than capable and love our sweet boy dearly. we trust them completely, knowing they will be so cognizant of jackson's medications, his little quirks, and his every need. he will be in such good hands, and that is comforting to know. this will also be such a great playdate for jackson with (almost) 3 year old cooper, and 9 month old mason. jackson needs socialization... bla bla bla...
i know all of this, really i do, but damnit this is hard. my emotions go absolutely nuts when i think that paul and i will wake up tomorrow morning without our little magoo in his crib. i will cry. seriously, i will.
we have left him before, with my parents, a few times. each time we have left him overnight has been because paul and i had an event, a wedding, a "thing" to go to. for some reason, this feels different. granted, we have the rest of our move to tend to this afternoon, but justifying sending our son away for that and for an evening to ourselves just doesn't seem right. right?
paul and i debated this last night until nearly midnight, knowing that jackson wakes up at 6:30... and we're hurting now because of it. more coffee please! these plans for jackson have been made for a couple of days, and i've let it all marinate in my head for a couple of days, but now we're at THE day.
so do we or don't we? (ps- we are anyway... but would still love the input.)
