Feeling so alone

Hey everyone, I don’t quite know how to tackle this.

I’ve been with my partner for over 5 years, he already had a daughter from his previous relationship. She is now 8.

We had our baby in Jan 2022. Since then I’ve felt like this is MY baby, he doesn’t help much, if there is a tough night it’s MY tough night, not ours. My son never settles with daddy because he never spends time with daddy, I spend every waking second of my life cleaning, cooking, planning and just everything that needs to be done in this house.

On top of it all he says that I don’t prioritise anyone but the baby, surely the baby is the first priority then everyone after?

How can I have the energy to prioritise anyone else when I do EVERYTHING in this house? I feel alone and emotionally empty, I am currently dealing with my son adjusting to a new time zone, we flew to the US from UK for a week and the past two nights have been hell, just for me because my partner will sleep and ask me how my night was in the morning. I don’t know what to do. He often complains I do everything but if I don’t do everything no one else will…

I felt so terrible last night that I started regretting having my son because of his dad’s lack of involvement
