Thank you soooooo much to all of you that replied to me! I haven't been back for a bit because things have been so busy around here.
Well, I have taken all the advice into account, and weighed every pro and con. I got the call just this morning with the official offer, and I decided to take it. I think that I will LOVE the flexibility, and the best part is that not only did they agree to pay me what I make right now for working LESS, but they are working on a 10% increase so that I will stay for a long time! I am ecstatic, to say the least.
I do realize that just because I make more hourly doesn't necessarily translate into more money in each paycheck, since the job is technically a 3/4 time job...but I have been assured that I absolutely can work 40 hours a week if I so choose, and my new boss-to-be said that he would line up as much extra stuff as I want. So, onward and upward!
Thanks again to all of you...I really appreciate your well-thought out advice.
