How to proceed.
Get a big case (if you are feeling generous) and put all his stuff in it, put it at the front door and get the locks changed.
If you are not feeling generous, just open the window and chuck it.
No, that wouldnt help you right now. Get down to your local CAB and ask them to do a financial calculation for you without him. That should hopefully give you comfort that you can pay your basic bills.
Be realistic about what you really need financially and not just wha tyou like or have become accustomed to. Deal with the basics for now and you can work out how to get the rest back when you are stronger.
Get yourself into your local community centre, family centre, surestart centre, area office, whatever, and tell them you are at rock bottom and need to find a support group or course that will help your confidence and self esteem. GO TO IT. Dont make excuses.
Then get the case......and do as above. And think about your child and what message you want him growing up with ALL THE TIME as you do the above.
Use MN to rant, rave, cry and ask for support.
And learn to look at yourself in the mirror and say - I am good enough. I deserve to be loved, I deserve to be treated well, I am more than a bucket, I am a person and I WILL be treated as such.
Cos believe me, there are a whole lot of good men out there, and a whole lot of confident women, you are just so low you cant see it right now. But if you take action, one day you will.
