SueW, I could have written that first part of your message, life was exactly the same for us, DH not working for 6 months, until Feb this year, kids used to a five star lifestyle, etc. Fotunately, DH is working now, when he does work he earns in a month what some people earn in a year. I'm not boasting, life like that, is like living on a roller coaster!
When we have money we spend it, when we don't, we economise and are very careful. The children are also aware of good times and bad, though they take a little convincing when I say, sorry I haven't got any spare cash at the moment. My main concern is always the school fees, as long as we can pay those, the holidays have to go on hold.
I'll never forget we went to a school meeting about a school skiing holiday and when they said is there any questions, my son said,yes, does the hotel have room service! I hid in my chair! It was also the first time he had flown economy!
When I suggest to the kids I get a full time job, (they are 14 & 15) they always say, lets not have this or that and you stay at home. They are used to it and thats what they think is the best thing in their lives- having had me at home all their childhood. They see a lot of their freinds from wealthy families, with everything they want, but also at a price - dysfunctional, fragmented, separated, etc
