Sorry, Stucki. I know that doesn't make you feel better, but I am. We haven't been talking long, but you are the strongest woman I know to have endured so many losses. I can never say I understand how you feel... but if I make an attempt to mentally put myself into that situation, I think I would be asking my doctor about sterilization as well.
I do think it's unfair to you to blame yourself like you're doing something wrong. All those pills, suppositories, tests, etc... I think you're trying to do everything you possibly can right. I don't know what's causing your RPL, but I definitely don't believe it's something you should blame yourself for. To blame yourself for something kind of implies you could have avoided it.
It is troubling to me that your husband isn't giving you any sort of support. And even MORE troubling that he seems to be saying a lot of cold things that would make you feel guilty.
I don't think I would be putting up with that shit. That's some kind of emotional terrorism or something. You have enough heartbreak without having to feel like it's something you're doing. Keep your head up, and if he's going to be that kind of an asshole, then I would consider leaving him. Not to "set him free" as you put it, but to set
YOU free. No one should be made to feel like something like this is their fault. It's sick and wrong.
Perhaps he doesn't realize that him talking about how his family line "ends with him" and so on is very hurtful to you? I would imagine you have talked about it with him? If you've told him, and he still continues to do it, then it seems like he is maliciously trying to hurt you. You shouldn't stand for it.
Sorry. I went on a bit of a rant there! Point is, if you need someone to vent to who won't pretend to understand what you're going through or try to relate their much more insignificant problems to yours, shoot me a message. I'll listen.
