Hi!
My husband filed for divorce six and a half weeks ago after twenty years of marriage. It was a total shock. I have spent many a day in tears just wishing to have my life back, but it isn't going to come back, even if he 'saw sense'.
You are in the first 24 hours. Just cry your heart out love. Just fucking scream about the unfairness of it all. I didn't tell anyone for two weeks, and the first person I told was my now solicitor. In hindsight, that was a mistake. Get people around you now. I tried counselling as well but sadly didn't click with my counsellor. Luckily an acquaintance, has become my number one pal as I learn to live with what's happened. Pay someone to listen, or if that's not possible, tell people - people will drag you out for coffee and let you cry your heart out to them. Embarrassing, but an important part of the dealing with it.
Do not let him make this a dirty little secret.
Not today, but later, imagine a future with that person. Could you ever trust them again? What about his constant unhappiness? It's draining. It is easy to imagine that it can all be fixed but you didn't break him. He broke you. He has to fix this because only he can. If he can't, you should be the brave one and walk away from the coward.
Your self-esteem will be through the floor right now, and will remain there for some time. That, I think is my second piece of advice. Find things that distract you, perhaps make you feel distracted, or comforted, or dare I say, give you pleasure. Find things that will get you out of the house and doing things. Talk to people, do activities. These will all help you build up your sense of independence. Find your selfish gene!
I have no doubt that times are so hard for you now, and you'll be very frightened of the future. I am still scared each day, full on terrified at times, but what is helping me is to build a little dream of my future, where I am back to my best: happy and independent. It's too soon for you to do that, but rest assured I have met so many successful women whose biggest mistake in life was selecting a shit husband. You aren't alone, and his mistake, will ultimately your mistake.
And if nothing else, write him angry letters that you never send!
