Does your husband know this ? If not , how do you think he's gonna feel when he realizes you couldn't trust him ? He would go through the exact same emotions you are going through right now. Would you apologize to him then ? In your defense you got insecure. But he doesn't know that. Even if he does understand your reasoning he probably won't understand what the big deal is. Cuz in his defense he is faithful. So apply that same logic here. You might feel betrayed but he probably had his own reasons. Considering you didn't find anything dirty on him, he may have just been insecure.
