The main lesson i learned from my recent breakup is to trust my feelings. I knew exactly when things started to change but i kept making excuses in my head that it wasn't true - but i knew. And as time went on and i knew it was getting worse i still kept talking myself out of it. I would tell myself "ahh she's just stressedf form her kids" or "maybe its menopause causing her moodiness". Next time i start to feel something change i'm going to be persistant to find out what it is and if i can't, i'll leave and not put myself through months or years of torture.
I also learned to keep the main goal fresh in my head. My main goal is to find someone who i have a lot in common with. I knew early on that this past woman would be a problem because she let her kids run our relationship. They tortured us and she had them 24/7 because her ex husband (who i had to take to court over harassment) never took the kids...ever. I knew early on that i would next to never be alone with her and that was a MAJOR problem in our relationship that caused a lot of stress. I will never ever date a woman again who has their kids 24/7 with no break. EVER
