There are some irregularities in your bank account and credit cards.
This one hurts, but yes, it is one of the signs your wife is cheating on you. If what she tells you and your shared credit card’s latest transactions don’t match, you might want to have a serious conversation with her. Also, if she starts paying with cash when she always paid with a credit card, you might want to ask her what changed casually.
She gets a separate credit card.
If you’ve always lived like this, then it shouldn’t be concerning, as many spouses have separate accounts. However, that, added to a ton of marital issues and fights, might show that your wife is, in fact, cheating.
Again, when it comes to signs your wife is cheating, opening up a new credit card might not be convincing, but if you think about it, the best way to hide expenses is by getting a new account. This way, your spouse won’t know that you are preparing for divorce.
