Am I wrong? Opinions?

Sorry in advance but its kind of long I just want opinions, thanks for reading!

So a little back story I am almost 19 years old and my brother is 20(we’re the only two he never supported like he should have) anyways when my father met my mom she was 19 and he was 29(I think alone that’s disgusting for him to look at someone that young) ANYWAYS... by the time she was 20 she had my brother and me 2 days before her 22nd birthday! Anyways he’s always been in and out of our life we were the biggest secrets until Easter of 2005(we were born in 98&99) we finally were good enough to meet his family from then on he was in and out and I only kept in contact with my older sister my older brothers hated us because we were “to white to be their siblings” by February of 2009 my dad had told us he was “coming back tomorrow to take us to the movies” and we haven’t seen him since! The saddest part is he left us high an dry with my mother suffering from MS and just lived his life... well a couple days ago he thought it would be ok to message me this!!!

DO YOU SEE ANYTHING WRONG WITH THIS or am I over reacting? Not an “I’m so sorry” or anything he’s blamed my mother for everything when it was him I’ve seen ALL the emails... what does he mean stay in our life longer and go to prison?! The only thing I can think of is kill my mom honestly because she wouldntget back with him! From 9-18 she use to try to force me to go there but i would beg and beg not to because I got beat, made fun of and everything else when I was there! I remember being forced to sleep with pit bulls and almost killing myself with a gun because he had them in every room without safety’s on my mom STILL never denied him anything she has and always supported us on her OWN! So I don’t even know why he thought it was ok to mention the stuff he SPONSORED LIKE UM WHAT? We are his children if we weren’t a secret he wouldn’t have had to pay for a hotel! He’s never paid for anything I’ve gotten two present from one was a bed frame and the other was a little electric motor cycle... like what the fuck?

How would you feel after 9 years of not seeing your father then he sends that!

How would you even reply back to that? Like my mom did a damn good job on me and my brother we’re kids only children that graduated both hs and college were very productive adults what the hell did we do to deserve such a poor pitty me waste of a father
