How do you end a marriage

[Whataroyalannoyance]

I know that this sounds really stupid, but how do you end your marriage. Been married 16 years, own a house (mortgage free) 2 kids, we both work earning the same.
I am very unhappy in the marriage, he won't move out so I will have to. The kids won't want to stay with him, he's uninvolved, defers to me on everything.
What do I do first? Start a divorce? Find a place to rent? Tell the kids before or after making decisions?

Find a place to rent. Do the online divorce thingy. Tell the kids after you've made your decision.

Find somewhere else to live as checks for rental properties can take a while

Tell your husband you want a divorce

Seek legal advice and get the ball rolling

Tell the kids after telling your husband and arranging somewhere to go

Get used to the idea of not having your children around all the time, they may not want to stay with him but he can and most likely will get some contact time. Prepare for the worst as in 50/50.

Financially if you have a joint account I'd close it before telling your husband if you're worried he will be spiteful, when telling him of the plan to divorce send half what was in the joint account at that point.

Aw so sorry to hear this but at least you have a job and are mortgage free ? I think you should consult a solicitor first. Dont tell the kids til you really have to. Can you go to relate first? Xxx

I've told him I want out. Should I start by separating finances?
I know how clueless I sound but I am overwhelmed at where to start

No fault divorce comes in from April. Make plans now, put them I to action then.
