Some really lovely comments here- id love to adress you one by one but there are quite a few so thank you all (I've read them all) 
And yep, I did miss 2 pills, didn't realise id be having sex (I'm not saying it isn't up to ME when I have sex but that's just how it was at the time and it is done now)
You're right about my husband being self employed (and before anyone says it- he actually does pay tax) he doesn't earn loads but he earns more than a lot of people and it was enough to feed the kids, keep the roof over our heads, pay the bills.
I even managed to get some savings together over a few months (not much but its the difference between me feeling a bit more secure or me being in a huge panic over money)
I won't be getting back together with my ex and I'm happy that now I can leave the dishes over night if I'm too busy with other things and DSs are allowed to put a tiara/fairy wings on without being told to take that off now!!! Mine and DCs best times were when ex was working or work then straight to pub and it was definitely the best choice to split with him.
So, I rang him earlier and asked if he planned to pay anything towards his children which he didn't seem to understand, he couldn't get his head round the fact that we are not together BUT our children still need money!
In my opinion it was pretty brave of me to ring him, he could have came round the house and kicked off, I know of women who are travellers or were married to a traveller that left their husbands but it would always have to be in the night or while he isn't in, pack a bag, get the kids and go. I just packed his things up put them at the side of the house and when he got back from work I explained it to him and went back inside the house, told him I was ready to ring the police if I needed to and he left in the end
Some of the 'traveller traditions/culture' is ridiculous but I do see things changing, they can't all ignore what the rest of the country is doing for much longer. I'm not even against meeting someone new in the future, not thinking about that much yet though
Well I can't predict what will happen with money but if the government do let children go without enough benefits then that would be terrible, not the kind of country I thought we lived in. There's not much I can do about any of that apart from carry on being as frugal as I can and trying to save any money that I can
