JP so sorry you are in this situation. I KNOW the agony you are fee,ing, the mixture of shock, disbelief, anger ,hate, saddness and love it's a hige rollercoaster of emotions you've just been forced onto.
4 years ago my world fell part when my dh- my best friend, lover, the person i'm the closest to in the world had an affair with a work colleague. we'd been together at that point 20 years, married 16 of them and had/have 3 great children. I felt an absolute MUG- I had no idea, never saw it coming- thought all was ok with us. Infact nothing major was wrong with us we'd let life get in the way of us and he had some sort of a 40's mid-life crisis and completely lost the plot for a few months.
We are still together and I can honestly say now we are closer and stronger having worked through the agony of this trauma together.Until you live through something like this no one can explain what it's like- it's very easy for people to say "get rid, kick him out" but you know this person so well they are so much a part of your life and you are suddenly faced with the fact that "he's lost it" you'll be feeling like your living in a soap opera at the moment , like it's not your life and the fact that none of this is your doing and you had no say in the choices he made are very hard to cope with- for me i weighed up what we had together before this and decided it was worth fighting for.
We both saw counsellors, seperately. me , to deal with the overwhelming emotions that invade your every moment and can so quickly become so destructive to any future you may have. for him to try to understand how he got to where he did.It took the best part of a year to totally get HER out of our lives and we made big changes- time for each other, decluttered our lives and focused on our family.
I would hazzard a guess that your dh is approaching 40 and the living away so much has a great deal to do with this!
he needs to decide where his priorities lie and make drastic changes- he must put you first and do everything to try to make you understand why and how this happened. men in this situation have a great ability to put their lives into different boxes and put lids on the boxes at certain times- he has been living a fantasy, escapism- not necessarily escaping from you- just a different "fantasy life" at first this life is so exciting but when reality hits and the real world finds out these relationships seldom last because they have no substance to them they cannot exist from day to day.
There is hope IF YOU WANT to move on- but it involves lots of painful homest talking on both your parts and he has to tell you everything, cut ALL contact with her and focus on you.
My dh looks back now and says he can't believe what a fool he was, he nearly lost so much for so little but at the time he'd managed to seoerate his lives and quite simply chose not to think about me or the kids just himself!
Do i trust again? not totally 95% I'd say and i know it will never be 100% he's got to live with that he caused it! BUT if you can work through this together it can bring you closer and I think we both have better lives together now because we KNOW what he nearly lost for us.
Take care of yourself, whatever you decide you need to let yourself grieve (I'm sure that the process you go through is akin to grieving)do not try to bury the emotions they laways come out at a later stage- if you can both bring it all out "no more secrets"- it's the deceit that kills you- then and only then can you make some sense of it and start to heal.
I learned you don't have to forgive (after all some things in life are unforgivable) but you do have to try and make some peace with what he's done before you can begin to move forward. Good luck, keep talking it does help!
