She works out more.

It could be a mid-life crisis, or she might be finally getting in the shape she always wanted to, so this one, I have to admit, is incredibly ambiguous. Why? Well, here’s the thing: it’s very hard to tell if this is one of the signs your wife is cheating on you because she might be doing it for a better life and health, which is totally understandable.

You can’t reach her when she’s out running errands.

What if she’s tuning you out because she’s tuning someone else in? If your wife is always hardwired into her phone and then, all of a sudden, she’s not anymore, that’s questionable. Of course, you might want to give her the benefit of the doubt, but make sure you ask her why she is suddenly so unavailable, just to see how she reacts.

She’s out more with friends you don’t even know.

Sometimes, healthy marriages are strong because each spouse has their own separate social life. Spending time with your friends is important, and it shouldn’t be ignored. But if you notice that your wife is spending increasingly more time with people you don’t even know, you might want to ask yourself why.

Whether it is a sign your wife is cheating or not, it would be nice to know who she spends all that free time with, right? Otherwise, it’s as if you don’t know each other anymore, and that’s definitely not something you want to happen.

Long-standing friends will always offer you the chance to quiz them and talk about what your wife has been up to, but that’s just gone when she suddenly spends more time with the new girls on the block.
