In response to ur comment,

It is expected for either sides to act emotionally if they discover that their partner is cheating on him, it will be expressed into various forms, but

to be logical is the best solution, why destroy a relationship when u can fix it, try approaching ur husband in a nice way & let his feelings out, try asking him for example, what do u think of me? have I been doing anything u don't like? how can we improve our relationship? leave out ur feelings and listen for clues, there has to be a reason for him to cheat on u,

Remember: Both of u have to believe in your relationship, otherwise it will fall apart.

Wish u all the best!
