This is a difficult one, you have been together a long time, He lies, than in itself would make me question why I’m prepared to stay. Reason being if you can’t have trust n honesty in a marriage what have you got, he has now got health issues which are hard enough to deal with but with other factors in the marriage will make it harder to deal with, but you marriage hasn’t changed only got worse by the sounds of it, how much longer can you go on like this, it’s your second posting I believe, you haven’t mentioned the word love once, you say he’s a good kind man kind man, sorry I don’t think that a good kind man would lie to you throughout your marriage, I think you would be much happier on your own, if it was me, I would have a serious talk with him telling him how you feel and take it from there, but for me I couldn’t live with a liar,
