Alcoholic ex bf still an alcoholic

SORRY i had to let it out somehow... my ex bf was an alcoholic in denial!.drank all day everyday didnt eat food just beer. I was surprised he never ended in the ER.He left me for the girl he said not to worry about....she knew we were together and still texted him.no i dont feel bad he left me for her.that just makes her a hoe.i dont know if i feel bad or happy i shouldnt feel happy that Someone told me he still hasnt changed..when he left me he said he was gonna stop drinking change and get a good job...but he still drinks excessively and wastes his money on unnecessary things (rodeos, beer, clubs ) i prayed for him .but mainly for my self to be removed from this person.and i got my prayer answered its been a year since we seen each other we lasted 2 years together and my first and only miscarriage...But now that i found out he hasnt changed i have been thinking about them ... Idk why..his new gf has twin daughters idk how old but how can she be with him having kids!? How was i stupid to even want kids with an alcoholic my self!?? I wonder if he ever regrets leaving me or if she ever regrets getting with him😕😒 we would of been 3 years in march💔 he always told me i was the love of his life...yeah so much for being the love of his life right?💔
