This is what you are going to do.
Drink, throw up, sleep and in the morning, you will get up, wash and eat something. Call the kids to say hello and get dressed. You will do your hair and put on your make up.
You will pack your bags and go home. Collect your child and go home. Shut the door, lock it, turn off your phone and unplug the house phone.
Update facebook to "single" staus and then you will turn it off. Stay on MN and talk to us for as long as you want to. FB will have too many questions. Have a dvd and a pizza night. Take advantage of this.
Ignore any knocking on the door (except pizza man). Go into hiding to lick your wounds for another day.
Then you will get angry and this is the best bit. Take full advantage of this because this will be your drive and this is what will get you through this crap bit. Tell as many or as few people as you need to. Dump the wedding stuff at his mums, dress and all. Sod the fall out, that's his problem. He doesn't have anywhere to go? Not your problem. He's sorry? not good enough.
From now on, it's all about you and your kids. These are the three people that are your priority, you, your child and your unborn child. For the next few days, think about these three people only. Bollocks to anyone else. Build that bubble and hibernate for a few days. Nothing else matters, only those three people. Two of these people need you to look after yourself so you can look after them.
DO NOT be pressured into talking to anyone, espcially him, if you don't want to. He'll see your child when you are good and ready and not before. You need time, and a lot of it to think and plan your next move, either with or without him.
Remember, you are not the only person this has happened to. It may feel like it, but you're not. You are not the first or the last. If these other people can get through this, so can you. Remember that. You still have a family unit and your kids will be fine by the end of this because you will make sure they are.
You and the kids are your priority, you do what you think is best for them and you. No-one else matters one iota at this moment. No-one. Just you and the kids, and you'll be just fine.
