First I'm very sorry you're going through all of this. I know it's rough.
However, I have no advice for you. You've already put up roadblocks about what we can respond with. I guess my only advice is to reread your post from the perspective that you are one of the other posters here. If a stranger typed the above, what would you say to them?
Thank you for reading my long post. I understand. I made terrible mistakes here. none of our marriages comes with manuals and my roadblocks were unintentional. I failed to educate myself (early on) about all the strategies of marriage, u know, all the things people talk about on how to's and what to's.
I wouldn't know what to advise this person either, but that's why I wanted someone with wisdom or someone who has been in a similar situation to suggest something, instead of making more dumb decisions. Now that I have some insight into what and how things went wrong, I want a chance to fix it not ruin it further.
