why does family invites bring he best of us out

my husband would
say the worst time in our marriage would be when we where planning our wedding . that when we fought the most and was the most stressful . (by the way we where also buying a house and i started a new manager job ) 3 things they say are the most stressful .
any way planning a graduation party for a few 100 of your closest friends and family is like planning a small wedding .
Why do men think they can start getting ready for it 24 hours before hand while women plan for weeks or months before and plan and prepare .
now the rain mind you we have a huge three car garage and he decide somewhere he was not going to use it and we just do it out side . i have a great big , shady yard , huge kitchen to work for food . but now what RAIN , what to do with your few 100 guest if all come at once OMG i want to cry and keep thinking it wont rain will it ?
we will see as i am keep moving forward doing what i plan and hope it all works out (well how cannot it work out ) it what it is right ?
His bright idea at 6am this morning on his way to softball with oldest DD is to rent a uhaul for the day . unload crap in there and then reload by in garage . omg that sound a little crazy but could work . if he would of planned months ago he could of had it done already .
well my yard looks nice . i mess up and did not get the carpets clean and well ick i see white spot where i spot clean ick oh well life will go on.. have i said i am not doing this a gain girls all out of luck . just kidding but i will never plan my own wedding again would not do that again . i said that and mean that .

i have always felt bad about feeling like one child gets more from us then another and how to balance 4 child. when son came of co use he was are only child and he came with special needs so for about the first 10 years even after dd came he was are focus we spent a lot of time and attain . then dd got older and seem to need us more with school and sports friends girls things . then the little girls came and well they needed a lot but still a lot of attain to oldest dd with her sports ect . son seem to be doing good but felt like he need more . when all where little i would try to take each one out once a month so one a week just with mom to dinner , movie or shopping and dd would do the same with our son one on one time . our daughter also seem to need us now more . and our son off doing his thing with him self or friends and i wonder if we missed something . i sure hope not . it a balancing act with 4 kids let me tell you . i want them all to feel special , love and number 1 with mom and dad .
