is it just me or does he have some serious audacity to be annoyed with me about this?!
Take comfort that it's certainly NOT just you ... this is straight from the Utterly Predicatable Cheat's Script.
He is demonising you for having the cheek to suss him out.
I don’t know what to do now. He has completely shut down and being very hostile since I confronted him. We live in his house which he had before we married.
Try to ignore him, his hostility, & anything he says to you. Just keep your head down & play your cards close to your chest while you plan.
With a short marriage & no children, you are unlikely to benefit from any of his assets - but don't take anyone's word for that, see a laywer asap. Don't tell him that you are going legal. Don't tell him anything!
I am due inheritance next year which will enable me to get my own mortgage. Until then I feel trapped and have no one to speak to or anywhere to go other than to stay here.
You need to get into a cold & practical mindset asap.
And to divorce your cheat before he starts getting ideas about YOUR inheritance. That money is for YOU, & your future security.
If you pay anything toward mortgage.rent/bills - STOP. I repeat - your money is for you now, & YOUR future security.
I feel suicidal
He's not worth feeling this strongly about, & you will NOT be feeling this way forever. Hang on in here with the thought that feelings are not facts, & that feelings will change as you get past the shock & dismay.
