Anyone else feel like their partner makes parenting harder?

My partner is going to be traveling this weekend and I’m actually looking forward to things with the kids running more smoothly 🥲 tonight he comes home from work, the kids (2.5 years and 6 months) are wanting him because they have missed him, he gets overwhelmed, says “I walk in and the pressure’s on” and has to smoke weed to feel like he can cope with parenthood then he helps me make dinner and put our oldest to bed after I get our 6 month old down. He’s still high so basically the whole time I’m trying to get my 2.5 y.o. to bed he’s getting distracted, walking out of her room, she’s following him because she’s curious, I’m trying to get her back in her room to get her changed into a new diaper and pajamas and read books all while not losing my mind. It takes two hours to get her to bed. She’s short fused, crying, generally having toddler meltdowns because she’s exhausted. I’m so overwhelmed and frustrated at him I’m short fused and trying to regulate my emotions so I don’t blow my top about how frustrated and stressed my partner is making me. All while I need to finish my work (I work from home while taking care of the two babies) and get any type of “me” time but now I’m so overwhelmed and frustrated that I’m just going to bed. This happens every night. Is it just my partner that does this?
