While my wife was away...
Do you think your wife might have been unfaithful?
Yes, I get that feeling all the time.
It's understandable that you are concerned about your partner's fidelity when you're in a marriage and your partner is spending a lot of time away from home. Cheating is very emotionally damaging and is a large reason why people divorce. It would be a good idea to talk with a therapist to better understand why you feel so suspicious of your wife and to better understand if those feelings are actually warranted or not.
My friends think that I am turning into a crazy wife. I have some suspicions about the wife, but it's not certain.
Well don't blame her if you have no clue if it is true or not. If you can't trust her you might find comfort in couples therapy.
