Does it get better after becoming a single mom ?

I’m so tired of being in my relationship. I feel like all I do is sit in the house and watch the kids by myself and I just can’t take it anymore. I want a job and I want my own place. I plan on moving to another city but I need to wait until I have a little more money. I’m just so tired every day is literally the same and I feel alone even though I have a partner. I’m just so ready to move on. I feel like he will make me feel guilty for leaving him. Probably say I’m abandoning him and tell me why I’m wrong but I can’t stay in a relationship that is doing no good to me. I want a different life than what he is giving me and I’m ready to start my own thing. It’s just so hard right now to hold it together.
