Do i forgive my dad

My parents divorced when i was seven or around that time because i wasnt told but im pretty sure my father was abusive to my mom .

My sisters tens birthday is coming up in a few days and my dads girlfriend is making the cake but yk thats fine whatever cool except my dad is trying to make my mom pay for half of it i think it’s totally unfair because he didnt ask my mom if she wanted to make it  entirely organised by my dad he didnt come talk to my mom at all about this i think that my mom shouldnt have to pay for it but what can i do im only a hopeless teen tangled in other peoples problems and its effective to my other siblings .

And other to that my dad was extremely abusive and always angry to us for no reason .

My dad doesnt like me well im definitely not his favourite because im nothing like im more like my moms side of the family 

And tbh i dont want to see my dad anymore but i can’t choose that but im almost certain my dad was abusing me physically when i was young but im afraid to ask my mom if he did because she might tell him and i might eventually if it gets me away but idk if it was a dream or not because I remember multiple occasions of him chasing me through the house and im also afraid i wont have enough proof . 

Also spacehey is kinda dead but if anyone sees this please give me some advice thank you sooooo much 25/7/2025 00:32
