In as much as we crave the fidelity of our husbands we too have to be faithful not just sexually but financially, emotionally and in prayers as well.
No doubt in most cases some wives are the reasons why their husbands cheat on them. Most women, after marriage tend to careless on how they look especially after having one or more kids. Some have been caught on bed with another man other than their husbands, some have intentionally or unintentionally pushed their husbands outside with the way they handle things at home( manner of approach, close monitoring, suspicious of every move et el...)
Speak to your husband with respect privately and publicly. There is nothing a man craves for like respect. Watch your tone and words when speaking with him. If you are upset about anything, speak softly and respectfully and if he isn't in the mood to talk let him be at the time and find a better time to speak. Some if not most reasons for a man's infidelity is a nagging wife.
