Just to keep a long story short.
I did not have a goof a father going up. He had gambling issues, gambled all our money away, beat my mom, and is the reason we can't own a house until almost 30 years later, no money for college, etc. Never works, can't keep a steady job for more than a year, etc.
In recent 2-3 years, he moved to another state to work and me and siblings have not talked to him since, did not bother to check on him, etc.
He also doesn't speak English well and me and siblings don't speak the main language well and we're Asians and asians don't express feelings really with each other.
Anyways, today, randomly on a chatting app, a translated message comes by from my dad pretty much just saying things like he's sorry for the things he's done, how he's so proud of me and my siblings, how we should treat others going forward, wishing us well, etc.
I'm not sure how to respond to that or if I should even respond. I don't even know if I forgive the guy....
