Venting

I’m honestly shocked by how quickly people on here jump to “leave him” or “get divorced” based on one small glimpse into someone’s relationship. This sounds like a mama who is exhausted, drained and feeling disconnected from her husband and that deserves empathy, not an immediate instruction to break up her family.
Relationships can go through really difficult patches, especially after having a baby and when you’re carrying so much of the day-to-day load. I don’t know how old your kid(s) are right now but feeling disconnected doesn’t necessarily mean the love or relationship is gone. Unless there is genuine abuse or you areunsafe, surely the first step should be honest conversations, making each other aware of what’s going on, looking at what needs to change and seeing whether that emotional connection can be rebuilt. Sometimes it takes time and work to find your way back to each other.

Have you told him how you feel?

Most men by nature are selfish. They could never be in a woman's shoes, let alone a mother's. This is all too common to feel how you are and you aren't alone. BUT, and I am sure you know this...it is NOT normal to live how you are. Your body is sensing what stress he causes and to affect you so much that you felt necessary to sleep in a different room for a month is hurtful to even hear. I think therapy would be a good step if he isn't listening to you. An outsider that can make an assessment to show him what he is doing to you make speak higher volumes to him. For now, consider what other moves you can do to help yourself feel and stay more at peace. Life is so so short. Especially when you're stressed. You deserve to make decisions that give you happiness and breathe life into you. Make a plan B. Create a vision board. Make a list. And execute that list. Do it for you and your child. They feel your emotions and will live a better and healthier life with you being at your best.
