Thinking of ending my five year relationship :/

I need advice please

I’ve been with my bf for five years now we have two very young kids and we have been through a lot but it’s getting to me now because I have put up with so much and given so much and don’t feel like I’m getting anything back.

I’ve dealt with physical,mental & financial abuse and I’ve had issues of my own that I’ve just had to deal with he’s given me no support just tells me to ‘grow up’ and that I’m overreacting.

He uses work against me in arguments all the time. If I ask him to help with anything he won’t I’m left to do everything with the kids, all the house jobs I’m rushed off my feet all day while he’s just sat there... he won’t tidy up after himself, doesn’t cook even though I’ve offered to teach him he wont even learn stuff for the kids sake and I’m tired of it

Thing is now someone just asked me where do I want to be in my future and truth is not here practically looking after him like a third child :/

Anyone been through this ?

Should I keep trying to fix this or leave?

Would I be happier alone ?
