Ending relationship because he’s useless?

[HitBreakingPoint]

I’m considering ending my long term relationship because my partner is fucking useless (and lazy). We have young children, one of whom is only a baby.
An example of his uselessness is he works early some days so home before school/nursery pick up. Kids will come home from school and he’ll get them changed out of uniforms but doesn’t put a single thing away properly, so the next morning is an absolute frantic (resulting in being late) search for someone’s shoes etc. I could think of a million examples but they’re all along the same kind of lines. The long and short of it is day to day life would be so much easier if he wasn’t here!
The relationship is good otherwise, am I overreacting or is this a valid reason to end a long term relationship with kids involved?

Ditch him. The resentment will only grow. You don't have to feel gratitude for sub-par support. I'm a single parent (newly so, admittedly) and parenting alone is already a thousand times better than being with a lazy, unambitious drain on my precious time and mental resources.

He was a great boyfriend, but you made the fatal mistake of thinking he would automatically then be a great husband and father. Not the case.

He won't change. It sounds like he is doing as much as he is capable of. You are wanting and willing him to be a better version of himself. Not going to happen. Either live with it or become a single parent and do everything yourself with a lot less money and no loving partner.

Do you regularly undermine him in front of the kids (be honest)

Casper001 define 'undermine'.

Expecting basic competence and engagement in household tasks from the person who is the co-parent of your children is really not excessive. And repeated incompetence and disengagement should be called out - politely if at all possible, but nevertheless. When you're adding to the household burden by your actions, you need to change.

I had this with my ex

She never bothered to put anything away / left it where she used it and that was the same for the kids uniforms etc.
The solution ?
Got the kids to put their own uniforms / coats in the washing basket / washer and on pegs / their chair. Shoes went into the shoe cupboard I bought and in their own section .... done.

I stressed for years over this as it was me doing the drop offs before then frantically trying to get to work in 20 mins when the commute took 30 due to lateness after searching for items.

If they're lazy out lazy them

Surely I don't need to explain what undermine means...

My brother's partner is like this. He does loads around the house but it's never enough. Not saying OP is like this but if there is an element of this then the unhappiness could be projecting via the partner.

Is he lazy or does he struggle with organisational skills?

Because he sounds like me.

I'm crap at home stuff.

Casper001 it depends.

Undermining would be berating him in front of the kids. Having a conversation with him about mental load and the stress caused by him doing a half-assed job of things is not undermining.

I agree kids should be taking care of their own school stuff when they get in, that is a 5 minutes job - but OP makes it clear that it's a multitude of things causing problems, not just one.

I am a single parent and though mine are all at uni now I can honestly say that life was so much simpler without my husband around - he was great around the house when we married but that deteriorated massively. And we both worked full time the entire time too.
