A recent book by M. Gary Neuman, summarizes a lot of theories about infidelity in relationships In The Truth About Cheating, Mr. Neuman analyzes the hows and whys of men’s infiedity. According to Mr. Neuman, the following are signs that can be red flags that there may be a problem in your marriage.
1. He Spends More Time away from Home.
2. You have sex infrequently.
3. He avoids contact with you.
4. He criticizes you more.
5. He starts more fights with you.
But the good news here is that there are concrete strategies to turn around what might just be a period of disconnection and not infidelity. Recognizing these signs is important in staying attuned to your partner and as a sign that the relationship is out of balance and that some corrective action will be helpful.

Thanks for the wake up article. I see that those signs can not be ignored.
