VENT: Not one one of my close friends is attenting my engagement party...

I may be acting petty but I'm just really bummed that not one of my close friends is attending my engagement party! They all have something going on! One, I even went as far as to make sure she's available on the day of before choosing the date and even then..she's still not coming cus supposedly she has to work now. People who are not even close friends of mine are reaching out and wanting to be involved and even offered to help out...but the group who was important to me is just not gonna be there. One is working, the other is celebratin her 7 month anniversary (really??), one can't come cus it's on a Sunday and she has church...it just sucks. Anyone else have friends who aren't comin' through?
