Sleeping on the couch again

So my husband and I started cosleeping with our daughter when she was around 2 months. She was very colicky and it just made nursing easier. Well fast forward and she’s now 6.5months and still cosleeping. I’ve been sleep training her for naps and she’s great at them. Problem is my husband works a lot and wakes up at 5am everyday so when he goes to bed he gets SO mad if we wake him up. I can’t even sleep train her at night cause I know she will scream and we will just have to put up with that for a few days. This man has never stayed up at night with her or gotten up for her. I get so flipping mad when he complains about sleep!! Like I’ve been a walking zombie for months. Every time he throws a fit I just take my daughter and sleep on the couch with her. But I wish so badly I could try to get her in her own bed. Currently writing this while on my couch too. 😔
