decision making

Okay, so here's whats going on with me: My Dad messaged me yesterday and said "If we got you a good full time job and a great place to live (not with me) would you come to Perth?" And it's really got me thinking. I'm quite scared, it would be an amazing oportunity and there are many 'pros'. There is only one 'con' and it's pretty much I'd miss my family and friends here. It is only one thing, but it's a huge thing. Last night I was freaking right out on the thought of making this life changing decison, but now that I've slept on it I feel a bit better. I'm still VERY unsure as to what I am going to do, but I'm leaning more towards going at this point. I'd probably go at the end of this year or the start of next, and spend a year over there. But what if I meet my husband and never comeback? I couldn't, I want to come back! I will just not speak to any men while I'm there, my new friends will consist of only women, haha.
Something that is great is two of my friends have already said they'd think about coming with me, that would help. They were both pretty serious, but one more than the other. I would love if someone came with me. If I went I'd have to push myself into a new church, root myself in there straight away. This sucks though, I wish I could earn enough money in a job to pay bills, rent and other expences, and still have enough money left to come home every weekend. I'll miss my church! I could still go to my home church, it would be like I never left. But that is looking very unlikely. The flights would cost around $500 return, there goes that dream.
So anyway, I'm a little scared. Meeting new people and making new friends all over again. It's taken me two years to get where I am with my friens now, I love them, I can't imagine life without them. But I couldn't imagine life without Tasmanian friends, and Mr X, and I did okay. I know I'd be stupid to not take this offer. I probably will go, and that scares me because I have to say goodbye to my incredible friends. I've got this amazing oportuity, I have always had oportunity througout my life. That's Gods favour on my life.
