Don't move out!! With 2 small children, is he expecting for you to take them and move out? Where - to live in your car? No lawyer in the country would suggest that you move out, not his either - it's your house too, and the welfare of the children trumps all other concerns. Stand your ground. He owes you a clearer explanation of why he wants to end things, although he may never give that to you.

Even if you think there is hope for marriage counseling, use this time now to gather copies of all of the financials - pay stubs, credit card account information and balances, mortgage info, life insurance info, bank and cd info, any brokerage or security account info, etc. You need to have a truthful and complete picture of the family's financial situation. I'm guessing since he's said he wants you home taking care of the house and kids, not going to school, he's controlling the money too. Educate yourself here, for your own protection and that of the kids. You need to also investigate lawyers, and how you might pay for one. Once one party files for divorce, the financial are supposed to sort of "freeze" where no one should be making any major changes. If you fear he will file soon, make certain you have some money set aside for your legal defense. Take care of any medical procedures you or the kids might need. Get yourself into counseling, too, I can't imagine being in your shoes with such young children. Good luck

you should ask him where he wants the relationship to go exactly ? out of earth and into space ?
you should remind him that you have 2 children together and relationship in long term comes down to just living together, supporting and co-operating and being a life companion (that's as good as it gets), so what is he looking for exactly ? does he even know and whether he is being realistic about it ? of course, there are consequences for his actions/decision so if this does leads to divorce, he needs to compensate you and his/your kids for his change of mind (or mistake, whatever he is labelling this situation as) but still, not only for you and kids, also for his own sake, he should ask himself what the underlying issue is and whether the way he choose to handle this issue and the outcomes that follows is something he truly want and its best for him in long term?
unless he vows to live by himself rest of his remaining life, he will enter into another relationship and he will (as typically) have to deal with relationship problem (diff needs/wants/perspective/health issue/financial issue etc...) all over again and some may even be things that he took it for granted when he was with you and probably think its same smooth ride with others when it is not. everyone is different.
if he finds the relationship to be mundane (which what everything is in long term), you should both make effort to spice things up a little and makes things interesting by doing something different, different activities etc...
Also, although very hard, but as much as this issue is important to you and your family, try to control your anger/negative emotions when handling this issue as this only tends to makes things worse (most likely, he will avoid communicating with you and start to see you in more negative light which means less likely he will reconsider his decision) so you should avoid acting like as if this relationship is really over but give yourself some space and possibility that things can still work out. you should encourage open communication with him and talk about the underlying issue. hopefully, he doesn't break up already well established family just for his unrealistic beliefs/expectation that will only leads to futile struggle.

I have asked him more then once why he is basically telling me it was a mistake...i truly feel like it's some one else you was one day just telling me you couldnt live without ne now with no compassion you want a divorce smh...i asked for marriage counseling he said no...i will start the process of looking for a lawyer and ive been on indeed non stop applying for jobs...And your so right im not going any where i dont hve the money ill live on one side of the house he will hve to deal with it

I hve all of the finance info due to i handle everything he couldnt even tell u where the deed to the house is located...i file our tax returns and everything he has never had to handle those things

He probably wanted you to work part time so he did not have to pay you more spousal support when he leaves. I am sorry you are going through this with such young kids that need a full time Mom. They grow so fast, sounds like he was not supportive of you. I would get a good lawyer and start there. Down the road perhaps you could live with your parents until the youngest is at least 3. Maybe your parents can help with child raising too? At least you know he is not into the marriage, better now then 20 years of stress, still it difficult

You are so right about better now then later...I haven't told my family wat is going on. Im still working part time but looking for a full time position

Not to sound paranoid, but keep all those documents safe. As in someone else's house, or the attic in a box of old clothes. My ex took some papers which made it difficult to put my case together. Took them, denied it, then didn't have a response when I told him I found them in his stuff. Glad that you have a plan. Being angry can propel you into doing things that otherwise might seem overwhelming.

Your right tomorrow im takinh all those documents to work to make copies just incase...and i have been praying alot and jus asking got to remove the hate...when going thru a break up ita like death you go thru different stages of grief....right now im feeling ok tlking to ppl and thinking of my next plan im seeing a lil more clearer

My historybis very similar, he told me: I felt Lost, i Don't feel the dame for you. Etc and what hapend? It he reason? Another person.
Some people is Just dishonest and selfish.
But We are going to be fine and better. I hope so.
