Hi love-the tears will begin to stop when you change from hurt to hurt and angry and also when you start to see your recovery as a priority.
Gradually the periods that you dont think about it will lengthen and you can help this by doing a few simple thimgs.
1, Minimise contact with him for at least a month,can family do the handovers of dd and dont call or text him unless its to do with her or financial stuff.This will not only give you time to heal but also make you feel that you have some control over the situation.Avoid talking about him with others too,change the subject as soon as someone starts to talk about him,you do not need to know what he is doing.
2, If you are going to maintain relationships with his family then i feel they should know the truth about the ow.You dont expect them to take sides but you cannot live with this lie just to protect him or them,and why should you?
3, Make little plans for everyday,it maybe a visit to a friend,a picnic in the park with dd or even just agood film and a bar of chocolate in bed.
4, Go through your business,cancell anything you cant afford and re assess your finances so that you feel secure.
5, Try to eat,even just for the sake of it,if you are hungry you are more likely to feel anxious and unable to sleep. I know its annoying but exercise really wil help the symptoms too.
I know it seems the most awfull thing in the world right now but lots and lots of us have been where you are now and are still living great lives.
Its actually quite exciting if you think about it,a new chapter in your life,anything can happen in the future and you are now soley responsible for it.
I wont bore you with my story but lets just say i felt unable to breath from the grief and shock of what he did and so much fear for the future.
I am fine now,it does get better and every day is a day closer to feeling better. Good luck xx
