If you find her more interested in gossip and drama of other people’s relationships, this is a sign that she is feeling you out.

She’s wondering how you feel about affairs and divorce or separation. She might have some mighty strong opinions about it, and be totally against it on the surface.

5. She seems guilty.

If she is apologizing more or trying to pay more attention to you than before, it might be because she is feeling guilty about what she is doing.

According to Lillian Glass, Ph.D. in Oprah Magazine, you can tell if your partner is hiding something if “they are rocking back and forth” when they are chatting with you.

Perhaps it’s because she is trying to build a wall so that it won’t hurt so much when she leaves, or she might do the opposite and try to strengthen what you have so that when she leaves, it won’t be so hard.

If you’ve grown tired of one another, but suddenly she is interested in sex again and wants to try new things in the bedroom, it’s a sign that she’s having an affair.

This might also be guilt sex, especially if she comes home from being out “with friends” and suddenly wants to get frisky.

“Both decreased and increased levels of sexual activity in your relationship can be a sign of infidelity. Less sex occurs because your partner is focused on someone else; more sex occurs because they are trying to cover that up.”

She might be trying to undo what has been done with someone else. Emotions run high during affairs and she might find herself trying to avoid those feelings with pleasure.

7. She tells you she needs more alone time.

The opposite might happen as well: she might withdraw altogether from sex and intimacy with you. Also because of guilt.

She might say things like she wants to go away by herself – and she might mean it – but the point is that she doesn’t want to spend time with you because it makes her feel bad.

If you’re seeing this symptom, as well as some of the others in this article, it doesn’t necessarily guarantee that they’re cheating. However, you do need to start taking action to stop the degradation of your marriage.

8. She doesn’t invite you out with her friends.

One sign that your wife might be cheating on you is if she is suddenly spending more time with friends, but leaving you at home.

If she isn’t inviting you out or is insisting that you stay home and watch the game, you might be right to be concerned.

“The cheater’s friends often know about the infidelity right from the start, and your own friends are likely to find out long before you do. This knowledge typically causes these individuals to feel uncomfortable around you.”

She’s not giving you all the details about the get together either: not sure who will be there, not sure what time she’ll be home, not sure what the plan is.

If you insist on going, she’ll get mad. It’s easier for her to keep you away from what’s really going on.

9. She has started to talk about the future in a different way.

If she used to talk about the future and use the word, “we”, but now talks about things she wants to do alone, that’s not good.
