Sorry d'oh, I don't know why I thought 4 kids + hubby, makes five kids.
When he married you, you became a family unit, He took on the responsibility of being a step-parent to that child. Morally I think that's how it works, legally.. it IS how it works. Whether or not he wants to accept that I guess is up to him.
It sounds like he is being very selfish. I understand that bringing in the money alone is hard. If he wants you to experience what he has done, should he not also "want" to experience what you have done? He should want to understand how you feel too. This isn't even about what is fair, it's about actual love. If you really love someone, you want to understand them, you make it a priority, and you do it out of free will.
It's silly to think we actually have to wear the other persons shoes, too understand that they might be uncomfortable, that's why we have empathy. You don't need to actually do what he had done to understand how it would feel and vice versa. Tho some people do not seem to have the ability to do this.
You need to keep your self esteem in place, and build on it. And that is impossible to do if someone is constantly ripping it apart. That is very abusive. That is trying to rob someone of their very basic survival.
I can't wait for you to experience peace and harmony, everyone needs to have that. It isn't a luxury, it's a human right.
Just know that whatever you decide to do, you have support here. If you decide to try to make it work, we can offer you support, if you decide to make a plan to leave than you will also have support for that too.
