Maybe instead of just giving up on the marriage and making her trust issues worse, you should work with her to fix it... Maybe do some marriage counselling or something.

Sorry to hear that OP sounds like my ex. She accused me of cheating while I was at work to support her and her daughter. She has terrible anger issues and was convinced everyone was out to get her. The next day she was sweet again. It was never going to get any better and nothing was her fault. Get out while you can.

maybe she's cheating on you

So she wasn't this paranoid before you got married? What changed?

So maybe try talking to her? I would assume you already had but be sure to try everything to fix the issue or reassure her before resorting to divorce!

Wow, divorce because she loves you that much. Yes, she has issues and could use some help. But giving up like this means you probably never really loved her in the first place, which is probably what she picked up on and interpreted as infidelity.

Why is she so convinced that you're cheating on her? That's just weird. Sometimes they say the cheaters always think their partner's cheating so maybe you should start spot checking her

I think people need more information on this before they jump to conclusions. Maybe the OP is innocent but does suspicious things like staying out all night, coming home late often, etc. Maybe she's getting defensive and looking more suspicious. We also don't know what happened with the firing. Did they leave 5 minutes early and the boss got mad or was she running in and out, coming in late and leaving early every day? I'm just saying, maybe she has been dealing with an irrational person for a long time. But we have only heard a small part of the story from ONE side.

I ran out of editing time. I was trying to ask what are the spot checks? I mean it can mean OP may see her drive past work or she may get a call during the day asking, "What's up?"just as a nice gesture. Paranoia can go both ways. I have no idea who is or isn't wrong in the relationship. People have said maybe the wife is cheating and wants to divert blame. That also goes both ways. We need more of the story.

Good abput divorce, but that's why you also move out.
