First of all can I say how much I feel for you and all your pain.
I've not been in such a situation myself but what I'm reading between the lines is how you are such a selfless person. You have an amazing quality which makes you an amazing person.
Although I haven't been in your situation, what I do get is that you do not want to rock the boat for many reasons.
I was in an unhappy marriage and had a young daughter. I didn't want to leave because all I saw was a load of pain ahead including finances etc. Mainly I put up with everything for the sake of my daughter. I didn't want her to go through all of that turmoil, i.e. I was trying to be selfless.
Then I found out that my wife had been sleeping around for some time. 11 different men in total.
After a lot of pain and suffering I knew that the balance had been tipped and that I needed to go.
We were also always overdrawn, me a few thousand with my bank, and I was always trying to be conservative with my spending. During my thought process of trying to decide what to do for the best I noticed that she had been spending hundreds of pounds on sex toys. I have no actual issue with that, more that we were struggling financially but she was spending all of our money in the wrong areas, at least that was my perception.
So despite all the negative thoughts running through my mind about how difficult it was going to be, and asking how I was going to survive financially, I finally made up my mind to get out.
And do you know what I discovered?
All of the things I was thinking about in my head about how this person would feel, how that person would feel, how my daughter would feel ...... you just get through it somehow. Don't get me wrong it's not easy - but you find a way.
9 years down the road and I realise to this day how it was the best decision I ever made. Sometimes you just have to act, especially if it's making you feel so unhappy.
Everyone in life is entitled to be happy, including you. x
