Is this really going to happen?

Hubbie had a meeting this morning about a possible job opportunity in Oman, yes, Oman! Although I appear miserable most of the time I actually quite like my life here, good social life, kids settled in school/nursery, family on the doorstep to help out and I've several others stressed out mums to share a glass of wine..make that a bottle with. So the thought of uprooting my 3 daughters, the youngest being 6 weeks!, is making me feel quite nauseous and I'm kind of pretending that it's not really going to happen. I've been googling Oman on the internet and it looks quite a nice place, in fact a few weeks in the sun would be quite nice but moving our entire lives to another country completely overwhelms me....who does that? Pack up their house and just disappear leaving everything behind, it upsets me to even think about it. Hubbie appears quite excited about the whole idea, and it could be a great opportunity, that's what makes this whole thing so difficult because I know that if he turns it down, it'll be one of those 'what if' situations. I think I need to try and be more positive about it, I mean, it won't be forever if we do go and we could save some money to come home with. Yes, keep saying it and I might even believe it.......
