Hmmmm, firstly sorry to hear that the GP was not immediately responsive, but you have done something there.
If he can out & play golf with his father who in turn cannot discerne any difference, then I start to wonder further about what is going on. Can your DH out on such a good front? Is your FiL taking matters at face value?
Have they discussed matters & somehow agreed least said, soonest mended?
‘Hey Son, what’s going on? Bogie sleeping on the sofa? What’s all this about? ‘
You must not leave your home - for your own sake & wellbeing, & for the sake of your children’s wellbeing.
If the game at play is one of let’s pretend nothing’s going on, but Bogie is taking the brunt, then I strongly urge that you call time on this fiasco.
As soon as you can, go see a family law specialist, describe what had happened, how he has raged, thrown your marriage in your face, stonewalled you & will not work to resolve this.
Keep notes for reference. The first session may not be at full rate, or even free, so do not let cost get in the way. Your purpose is to tell all to the solicitor & be advised about
a) divorce on the grounds of unreasonable behaviour;
b) how to legally separate & stay put in the marital home
c) your rights if you separate or divorce.
At this stage you have need of professional advice so that you are better & fairly prepared for what is to come. You need to know where you stand. This will give you confidence, self belief & resilience as you know better for & about yourself than he does.
Two more things:
- Did you say that he came home from the GP with a sick note which he left out for you to see? How would you usually discuss things like this? It does seem odd to me that he would not sit & discuss this with you. Somehow it feels to me like he playing a card in a game - putting it out in plain sight as a reveal - could be disordered thinking or plain contempt ?
- If his father thinks he’s OK & nowt wrong, I suggest that he go stay with him right now. He’s signed off so relocating is not an issue for now. Pack a bag for him if you must. Your being consigned to the sofa by his rage & stonewalling you is unreasonable & unacceptable - it is the thin edge of a pattern of domestic abuse.
You will get through this, it’s horrible now, but things will change.
