For me it was trying to emulate my parents and GPs marriage. Thinking I should just accept my fate to stay married. To work through our issues and learn from them. To not give up when exDH was being a pig. To stick together no matter what. Well, that didn't work. Financially, I was screwed if I left him. I was also critically short of self-esteem.
Although my parents have been married over 50 years, for ny mum, on being told I was divorcing, was mostly concerned over the welfare of my daughter and me. She and my dad acknowledge the world has moved on since they got married and, when I saw the light, that I had to do what was right for me and their granddaughter. I thought they'd be ashamed of me, but that's not the case. The so-called idea of sticking together no matter what in order to get my 50th anniversary chip wasn't achievable and it was ok.
I think women don't think they can manage alone, until they have to, and most do, and can, with amazing results. We are too often stuck in situations that we think we can't get out of, but it's possible. Nothing is 100% impossible. Self-esteem and loneliness plays a huge part. Financial reasons are huge. Even when we complain to our partners and say, you need to step up, I need more support, we're told we're nagging and needy...no, we are telling you we need help and you aren't delivering! Gaslighting and placing blame back on us also has huge consequences to our sense of the truth of things... second-guessing yourself all the time. It's hard to know if you are doing the right thing by standing up for yourself or if what you know to he true is actually a fantasy in your head. I battled with these feelings for years.
