I'm upset that my spouse does not tell me what time he will be home
Is there something about it that makes you scared?
I just don't want to be with him anymore.
You should just break up then if you're not thinking of long term commitment, it seems that your relationship isn't that great if the two of you can't let each other know where they are. It's only common courtesy and respect like that which should take place.
My spouse thinks that I'm the one who will break up but I know he's the one who will break up with me in the end.
It is normal for people to tell their partners where they are if you are expecting an event to happen. If you cant trust each other I would recommend couples therapy to work through your issues.
