There are many reasons for adultery. Maybe your wife is bored, perhaps she’s unhappy, or she thinks you are too controlling and doesn’t suit her needs. Whatever the reason for the infidelity, there is always a reason:
Perhaps your wife isn’t looking for an affair; instead, she’s just looking for more than what she has from you at home- which is probably all physical intimacy and little to no emotional intimacy. The following are some signs your wife is cheating that you should look out for.
1. Lack of attention for you.
Over time, your wife has become less interested in you. This can be traced back to being unsatisfied with how you treat her. She might have started taking long trips regularly; she might be spending more time at work, or she may be less interested in spending time with you than previously.
2. I’m going out for some fresh air
There is nothing wrong with having an affair, as long as you are not hurting your spouse. However, before you enter into an experience, remember that the person with whom you are having an affair is by no means your partner. If you feel guilty about it, it is important to express this to your partner. Remember that marriage should be a partnership between two people who have each other’s best interests at heart.
3. I love you, but I’m not in love with you.
Commitment comes with sacrifice because you have to make sacrifices for the person you love so much at some point in time. Such gifts will mean that 
you have to give up your usual behavior and then change it in favor of someone else. The thing with love is that you cannot force it. If your wife said something like this to you, it might signify that she’s cheating on you. Use the best spy app for iPhone to monitor her text messages, call logs, etc.
4. I’m going out with my friends tonight
Your partner’s life should not take a second seat to your friends or business interests. If she does not want to spend time with you and says that she has other people to talk to, it’s a clear sign that she can have a lot of attention and still not be happy. This is one of the most dangerous signs because, at times, we tend to think about our partners as being not very interesting or unable to keep our attention for long.
5. I love you, but I don’t love you anymore.
This was a big concern for me when my wife died. Now, I am not saying that it’s normal if your relationship is going through difficulties. I am saying that you need to make sure that what you say will not encourage any cheating on your part. It is essential to point out that you need to make changes to yourself and not expect all changes to be in your wife as a husband.
When all signs are pointing toward your wife cheating on you, you must take the time and sit down with her. Tell her exactly how you feel. Tell her that you love her, but you would like for the two of you to do some things together so that she can see what it is like when she spends time with you. If she does not want to spend time with you, talk about it rather than just finding an excuse to run off and have an affair behind your back.
