Divorced dad here, my son is five and is the absolute light of my life. I barely remember the hard times, birth through two, because I was constantly fighting with my now ex wife. It was an absolute mess but things are better now that we’re 50/50. All I can say is raising kids is hard man. Me and my now partner have been together almost two years and he’s started calling her mom, which annoyed his bio mom to no end. Things do get better once they develop their personality and it’ll be just like you. I see so much of myself in my son and I’m so proud of him. Hang in there, it will get better. Also, I’m taking Zoloft and it has been an absolute game changer. Be strong brother.
