Would you go?

One of my very best friends whom I've known for 10+ years now invited me to her Bachelorette party in 2 months. I just had a baby 5 months ago. Money is really tight. My boyfriend and baby's father will not want me to go, due to the fact I would be gone two days and it would cost money we can't really afford to take out of my savings. But I would really like to go considering this is one of my best friends and I need a fun weekend. I haven't had a girls weekend in 2 years and not since becoming a mom. Would you go?
