Hi Seekinghappiness,
Bless you another who's in a dreadful situation, its horrible to hear so many people in the same boat.
I too had a long relationship married 18 years last 3 were appalling, but i thought id answer and say hi! and tell you your not alone, and answer your post.
You are right you do deserve to be in a relationship were you are loved as much as you love and after 29 years you kind of expect that anyway.
Im not a solicitor by no mean's but iv been there so can tell you from my experience.
You mention the children, I'm afraid in my experience you can't prevent nor predict what the fall out on them may be, you just have to be there for them when they fall. you at the same time cannot put of ending your misery for them as much as you don't want to hurt them it does more damage letting them be in a hostile environment.
My dc are 17 & 21 both of them reacted differently and that was another story entirely as my youngest really became angry & ended up having counselling which has helped him no end, whilst the eldest bottled it all up for over a year then blew. It is hard but as a mum you will do right by them and support them and they will support you.
I found we have all been so supportive of each other since my separation and they have seen why i divorced him in the first place because of his ongoing behaviour , they actually think its better now he's gone.
You are right if you are going to do it then you are clearly in a better position if your children are still dependant.
You say you do not work as your a full-time house wife, (btw, this is work hard bloody work lol) but your husband will still need to support you & the children until they are both out of education.
Either by way of spousal maintenance, csa, mortgage etc.. each case is obviously different dependant on your financial predicament of course but he can't simply say no to helping you because you are divorcing.
Id ensure you are aware of all bank accounts, details of them etc.. should you need them in the future.
As far as your home is concerned the first rule the court look at is the children they must be priority so it is doubtful you would be made to move with dependant children not straight away and you would need to be allowed time to re-train get into work etc.. this is all looked at as fair and it takes time to do so. so it may be that you are able to stay there until a said time then you would be asked to sell the property.
They look at assets and try to make sure two people can be housed from the one pot if you like, my husband hide assets and did all sorts of awful things, it is easy to get tied up into so much in divorce and before you know it your bill is huge.
You wouldn't be eligable for legal aid unless god forbid you were in a domestic violence situation, i was but still did not qualify for assistance and in all it cost me £17,500 so it is always best if you can mediate and keep it civil so you can form some sort of agreement together.
But is often the case it at some point gets difficult and then mediation is not possible.
I know it must be awful for you now as you will have so many what if & butts, so many question's whizzing around your head.
But try to be strong focus on the important things if you have decided to separate make sure as i say you have everything you need, get advise too.
If you can't afford a solicitor then try citizens advise, or google divorce there are loads of sites up there.
Don't let him walk all over you, you don't deserve it. After all that time together and your 2 beautiful children, you deserve more!
It is not much to ask to be happy and you will, but you ned to be strong and keep a level head, my advise is stick to the relevant stuff such as finances and don't get swept in to the he said she said silly arguments that occur as they cost. My husband ran up the bill so much he was actually warned for doing it.
Unfortunatly no judge will look at past behaviour unless it they say is so bad it can't be ignored, and i found a lot of my husbands deceit which id proved got ignored by the court as they just want a resolution so any unfaithfulness is not relevant they say. Sad but true.
I hope iv been some help there are so many thing's i could say but don't want to go on so if you do have any more question's or need a gab a cuber ear ha! do pop on.
Good luck to you i hope which ever direction you choose it all works out for the best.
