When is a marriage over

Perhaps he’s abit depressed if he watches tv all day. Could be after retirement.
He needs goals and then in turn it might spark something.
Have you tried doing things together or talking to him about it?
I would want to make sure I tried everything before I left him. Good luck

Life is too short to live like that.

As other have said, a serious discussion is needed!

It is sad, but maybe if you could get him off of the sofa and get out and about you might find that you have more in common and can start to be friends again, after that who knows?

But not talking to him and turning these thoughts over in your mind won’t improve the situation, TBH I think that if the marriage was over finding somewhere else to live wouldn’t stop you from leaving, would it?

Take Taniths advice, sit down and have an honest discussion about what you both want, maybe he is as bored and fed up as you are?

By the sounds of it I think it could be time to move on . If you want to try to rebuild the relationship then you really do need to have a serious talk with your husband and see how he feels ,he might feel the same and If so it will be easier If you both want to go your seperate ways.
If you don't want to try to rebuild it then you need to start making plans . Accept that these things happen and sort out your finances .

That’s quite sad but if you are sure that your marriage Is over for you then you need to have a frank discussion with your husband before you make any decisions . Good luck
