After I had my daughter, I swear I've changed towards my SO... everything he does irritates me, I don't know why, I constantly have a attitude towards him. Like literally everything he does annoys me to the point I just want him to leave sometimes.. Has this happened to anyone else?
The best advice I can give you is to get out just the two of you. Get a sitter if you can or have a grandparent watch the baby. We never did that and we are not together now (not JUST because of that but I think we could have spent more time as a couple). Having a baby puts a LOT of stress on a relationship, especially a first baby. It's easy to lose sight of the twosome you were before.
I feel like this a lot. Today, we left my son with my parents and went out just the two of us for the first time since he was born. It felt really nice. Try that.
