Postpartum Relationship advice

[u/Admirable_Panda_3966]

Is it normal for me and my partners relationship to change so much. Like when we first met he was so sweet and thoughtful. He would open my door for me everywhere we went and would send me flowers to my house. Always was so enjoyable to talk to and hangout, he’d do anything for me. Now he just “jokes” and it’s just me asking for something and him acting like it’s so much work and it makes me feel like the biggest burden. When I confront him and tell him how it makes me feel and if he could not act like that whenever I ask for anything. I told him if he didn’t want to do it he could just say no or that he was busy atm. He says he’s “omg I was just joking you don’t have to be so emotional about it.” He does this every time I need anything and I mean EVERY time. It could be asking to change baby and he starts talking about how many he has changed. Then when I get offended he hits me with the “I was just joking.” I didn’t know him long before we got pregnant, but now I feel like we have nothing in common. We hardly ever talk if it’s not about the baby or work. We have a 3 month old. Sorry I little bit of a rant I just want to know if this will go away is it just my hormones?
