What about your sons? Do they not mean anything? Potential future grandchildren?
They're living their own lives as young adults do, but I am certain the atmosphere between you and your husband is making them even less present. You could have a lovely wee place of your own, join clubs to meet like-minded people. There are even holidays where you sign up by yourself but go as part of a group, everyone is in the same boat.
As everyone keeps saying, your H only earned all this money because he didn't have to look after his children or his home, your assets are from team work.
How are the finances split now? You say you don't have much money, does your H keep all of his salary?
He has crushed your spirit. You really, really need to see your GP. You have sons who love you and as I mentioned, potentially grandchildren in the future, have contributed to a life that will see you with enough money for a fresh start where you're not being walked all over and dragged down by the selfish, cheating man.
Do you honestly think in another 10 years he's going to be able to still live this lifestyle? That women in their 20s and 30s will be out raving with a man pushing 70?
10 years time and you'll have rebuilt long before. Have your sons, friends, a nice home that's yours and maybe even have met someone lovely who deserves you.
I can feel your hopelessness coming off the page and my heart absolutely breaks for you. But this is not all there is going to be. You will need help from GP, a (good!) solicitor, but you WILL get there.
Doing these things to give yourself some control back will help your self esteem. HE has behaved disgustingly and broken your marriage vows. YOU have been a faithful good wife and mother. You need to find that anger because I promise you, when you refuse to allow someone to treat you badly you will respect yourself.
You CAN do this, and we will all be here cheering you on. There are other threads with similar situations and the lovely ladies have thrived despite never believing they could, I'll see if I can link any and hopefully you will be able gain strength and clarity from them xxx
