Sue, you owe this man absolutely NOTHING! It sounds like caring for him is wearing you down, and how could it not after what he put you through?
I was born with a cleft lip, and at birth my mother rejected me. Don't get me wrong, I lived with her until I was 18, but that is all I did...live! There was no emotional closeness, no trace of love! I only had 2 ops. I was 9 when I had my last one & woke throwing up blood....my mother nowhere to be found. I cried for her & the nurse phoned her, but she needed to stay at home for work the next day. She rejected me over & over. When finally she told me, at 16, that she never wanted me & should have been allowed an abortion (my father wouldn't hear of it). Instead of making the most of it, of me, see used my cleft to distance herself from me. We haven't spoken for almost 20yrs.
4 yrs ago, she walked past me in a shop 3 days before I emigrated. She looked at me...she knew I was going & just let me walk out of her life. For good. I will never ever forgive her, and I will not ever contemplate ever caring for her.
To do so would crush me completely...to see to her needs when she couldn't see mine. No.
What I don't understand is this 'Dont get me wrong I make sure that he is well fed, warm,well looked after etc. I do this for my mum'
Sorry if this seems harsh, but where was she when he put you in care? Did she stop him? Because if not, your loyalty is misplaced! You are doing this, if not for him, for her....but she allowed you to be sent away too.
'I have four siblings who have literally walked away and I think to myself "for fucks sake I am not even in the fucking will and I am his carer", they hate him simple as that, but i try and have a bit of compassion and tonight I am struggling'
You are struggling because it sounds like you are in pain, that this is not what you want & that you want to walk away too.
If looking after him makes you feel good, makes you happy etc...then great! Continue. But in all honesty, it doesn't sound like you are either of those things, so I would advise you to think really hard about why you are doing this.
He said he sent you away because you are not 'perfect'. Are you trying to become 'perfect' to him now? Is that why you are putting yourself through this? Because as you said, he can't remember how he treated you, so you will never change his mind & become 'perfect' to him.
I am sorry if I upset you, but I really think you need to look after yourself! Sounds like you are drowning here, trying to attain the unattainable.
