Im a 50 year old mug

It took me 50 years to realise im a mug! Its all my own fault. I think it stems from my childhood trauma of my dad being an an AH and an alcoholic who wasnt very present and my mum who i adore having had it hard bringing us all up alone basically dissapeared to travel from me being 17. I have spent my whole life putting myself second to others feeling and only being okay when i felt everyone else was okay. Now at 50 pretty much all my important relationships like husband and BF are built on good ol me taking way more shit from them, always being understanding of outside factors for their behaviour but basically dont get the same understanding back in return. I am done with it. I have no bandwidth to do this any longer and i will not spend the next 30 years (if im lucky) being at the bottom of a very large stack of people when it comes to care and feelings. Watch out world cos i am done with it and am going to please myself a whole lot more and throw arsehole behaviour back at people in my life. I am not responsible for your actionsand do nit have to take your shit. Take some responsibility and dont look to me to say its okay because it is absolutely not okay.
