Solost - the advice on here as always is brilliant, I hope you are getting encouragement that things will get better and you will be able to deal with H more effectively, to minimise your own hurt.
I wanted to add to a few points already made.
AF mentioned the promises he made wrt to keeping you financially secure. My H has also said this. Like you I am totally dependent on my H financially, I work low paid part time hours. I have done so for 20 years since my children were born. A joint choice that I looked after the children, no childcare issues. But I have not developed my own career, even though I have a degree, I am now a 46 year old and would be competing with more highly skilled younger candidates. Those promises have been made by a less than honourable man, my H who I would have trusted 100% at one time, is no longer the same man. He was and is capable of great deceit. I would tread very carefully.
WWIFN mentioned getting the house key back. My H still has a house key. I have told him it is no longer his home, but mine and that he should respect my privacy, but he refuses to give the key up. However, he tells me he has never been in the house without my knowledge. Again he was once trustworthy and has proved to be a liar. SO how do I know if he lies about the house too.
We are currently sorting the financial arrangements through the solicitors. Mine is confident I will be comfortable. My H is a six figure salary earner. But this doesn't make it any easier for me to feel secure. I am having to fight hard. He has opened new bank accounts, and not told me, he has stopped paying his wages into the joint account without telling me, I have to ask for money, I asked for an interim agreement, he told his solicitor it wasn't necessary. Again this most loyal and honest man is proving that being embroiled in an affair with an OW that I have no knowledge of or her character, has changed into a person I do not know.
It is all very scary, but I have tremendous support from friends and family, and a lovely new man. SO I feel lucky and hopeful for a better future.
