How do you know your husband is cheating on you?

It sounds like you're dealing with a very difficult situation. My heart goes out to you. Often times signs of cheating can be subtle...different behavior, different reactions to day to day things, perhaps a shortness of temper or being accusatory. I truly feel that if your "gut feeling" tells you something you should listen and seek answers. Perhaps try to communicate with your husband and also seek support for yourself. Regardless, if you're feeling this, then something needs to be addressed and worked through. I wish you the absolute best and hope you can find what you need through this!

This situation can be really tricky. There may have been instances that you came across that raised your suspicion and guided your thoughts towards this. However, we should never assume the worst. The key here would be to communicate with them. Keeping a suspicion as serious as this within can lead to further problems and may show in your daily interactions with your husband which can lead to further misunderstandings, escalating the situation. Talk it out, be open and regardless of the outcome, you'll feel lighter taking the burden off your chest whilst showing your concern to your husband, who will hopefully communicate his side of the story to you. Best of luck, and I hope everything works out!
