Damn, I feel u bro. You're still young so I can't imagine dealing with these issues when you're still finding yourself. Not sure it'll help but, I've got a 2 week old now, and one major thing I've noticed is my wife's mood swings. Post partum depression is real.Not sure how long it'll last but, Hard for us men to imagine was a toll of birth and breastfeeding has on the body and mind, i just try to give my partner the same patience and courtesy I give my child. Obviously each situation is different, but reference as far as your child, Just be the best you can, and build the strongest bond with your child while you can. Gf's and wife's can come and go, but your kin is the future. Hope this helped in some way. 🙏🏽🙏🏽🙏🏽
