It wasn't much later when I had my own child, they finally broke me. Not only they set high expectations for how I will help them have relationship with their grandchild, and criticizing our parenting, but also started criticizing 2 year old. For their part as grandparents, they did bare minimum, that is attend a birthday, ask for pictures because relatives are asking for photos. Never made an effort to come visit us. That is when they broke something in my brain.
Now I resent them more than ever, I wish I had never let them criticize me as an adult. I lost faith in God since they are so religious. I am trying to be complete opposite of them. I have mostly stopped feeling joy. I live mostly to fulfill my duty as a father. I really want to pack everything and move to the other side of the world but wife doesn't agree with that.
And as a father, I realize that there is no sacrifice in parenting. You choose to be a father. That was your choice. My kids are the only things that bring me joy right now. Yes sometimes they push my limits and I am tired, but it was my choice to have them. Thinking that my kids are making me sacrifice will probably make me resentful towards them. When I am playing video games while tired because I am so close to finishing a level, I don't say I made a sacrifice.
EDIT: I want to add that I have lost joy in everything related to my parents like my culture, songs that I grew up with, religious festivals, food, stories, career, etc. I hate it.
