I failed at romantic relationships - I have had three five year ones that I ended, all because I saw the problems and chose not to act on them.
First one - he was a knob and I lost respect for him. I knew that right at the start but didn't want to end it. Five year later I ended it.
Second one - mean personality and sexual problems. Sexual problems were evident early - I thought it would get better, it did not. When I ended it I didn't even like him as a person.
Last one - had serious debt and just could NOT manage his income. I thought I could help him, which I did, but he was never out of debt and his attitude to money was 'I want it, I'll pay the higher interest rate for people with debt problems.' That said a lot to me. Should've realised it when he first told me how much debt he had.
What I learned -
Stay lighter on my feet emotionally - I might need to leave.
Take things I see seriously - crap sex? Debt? Rolling me eyes at him? That's how things are going to be.
When the last one ended, I thought to myself 'I caused this. I knew it but didn't act on it. I HAVE to get it right this time. I can't waste my time and their time when I know something isn't right. I wouldn't play the wrong note knowingly (I'm a musician) - why do I tolerate men who are not right for me??'
I also used to try and help men become better - no way now. I learned that if the shoes don't fit, don't buy them.
