Is this normal

Kay

My daughter is 2 weeks old. I have found that i am very envious of my boyfriend because hes able to get out of the house to work and just be away. I also feel like ive gotten a lot more insecure and i accuse him of cheating even though i have no reason to at all. i always bicker and start arguments with him. he tries to help me with the baby but all i do is critique everything he does even though he is trying his best. i always shit talk him and i dont know why and i can tell on his face that its dissatisfying of course but he puts up with it. i was never really much of a dick to him before the baby but idk.. im just so rude to him now and i dont know why. i know if i keep it up that it will be a real problem in our relationship. i just want to know if other women are experiencing the same and what i can do to just quit it.. i feel bad afterwards but ive apologized so much that any more apologies wouldnt mean anything
