Venting

So my fiancé and I are new parents to a 5 week old baby boy who we named Orion Nikolai. Everything the first couple days were going good but once we came home from the hospital it kinda went downhill. Like my fiancé works a lot and pays for the bills. I’m super thankful for him but at the same time I kinda resent him. Like I get it you work 10 hour shifts and sometimes do overtime and all you wanna do if relax and play video games for a few hours before going to bed. But what my fiancé fails to see is that I’m constantly up with our son and never get a break. He complains about being exhausted but what about me? I literally barely sleep at night because I’ve always had trouble sleeping and even when our son is taking his naps I’m up doing stuff around the house, so when do I get to sleep? I even had to start using formula because I haven’t been producing enough breast milk, which has totally been a low point for me. I, myself feel like a failure that I can’t make enough milk to feed my child and need to supplement. What really gets me sometimes is I’ll be talking to him and he literally zones me out and gets mad when I get mad at him, like seriously dude! Like today he stopped playing his game to take Orion from me to calm him down but instantly gave him back after he spit up a little bit on him, does he fail to realize that I’m literally covered in spit up almost 24/7? My biggest peeve with him right now beside the zoning me out, is that he promised me a deep back massage and only gave me a half-assed one, but he wants me to give him back scratch’s and rubs.
