If you think your wife had affair with a coworker you should know how to handle this problem. Affairs of any kind can ruin lots of relationships may it be your own primary romantic relationship or your relationship with your family. Most importantly, if individuals have an affair in with a co-worker it can ruin their career as well. Romantic relationships at work are not highly advisable and affairs in the work place are seen as more dangerous.
When people at work, you should always remain at your most professional state, but how can you do it if you have relationship worries at the back of your mind. If you think that your wife is having an affair with a colleague you have to be equipped with the right amount of information to figure out what you have to do. First and foremost, to check if your wife had affair with a coworker, you must check her usual work schedule first. If you notice that she is usually late from work almost every day you might actually have a problem. Much worse is that if you notice that there is a weird colleague of hers who keeps on taking her home from work. This person might actually be the one who your wife is having an affair with. But instead on jumping on to unjustified conclusions it is better to investigate more.
Another thing to look at is the amount of conversations and quality time your wife is spending with you. If your wife is spending less time talking to you and going out on dates with you compared to what you two have been doing before then she might actually be in an affair. At the end of the day it is only you who can solve and fix this problem.
