I find myself daydreaming of not being with my husband.

Somethings wrong here. We’ve been bickering a lot lately and it’s making my anxiety skyrocket, which I suffer from. We mainly bicker about our daily responsibilities and who is doing what. We also have an 18 month of who is teething, sick, and going through her sleep regression and is waking up at night. Which also doesn’t help. I don’t know what to do. I love my husband and I want to be with him, but day dreaming of not being with him is a major red flag. I’ve tried to talk to him about our bickering and we both agreed we need to communicate more, but it’s just not working...I’m unhappy and I don’t know what to do. Help.
