Fraternity Bid

Hello,
The day before yesterday was my last fraternity rush event I had attended with my friends. I was shooting for PI KAPPA PHI in Purdue University West Lafayette. The thing is my both friends got the bid and they accepted it. However, I didn’t get it that day(the got it the day before the last event). Is it possible for me to get the bid now, a few days after the last rush event? I started a bit late, I have only attended the last 3 rush events, but so had my friends(they got on the second last event). Also, if I do not become a member of the frat, can I go to the parties with my friends, make friends and have fun just like any other brother in that fraternity. I wont lie, I am very desperate to join the fraternity. My entire social life lives and dies with it.
I don’t know if I want to join any other fraternity.
