I found out my husband lied to me Months ago.

I'm really upset and am kind of out of place because I'm unsure of so many things. Back in September I threw a huge fit over him always taking one of him employees out for lunch and this one day he called me up and was like "I didn't get to finish the whole recap with her, I'm gonna take her to dinner and finish up" I was like ummm okay ? Anyway , were doing counseling together And I brought this up. The counselor told me that "it was okay because she use to be a big business person and sometimes she would have to get dinner with other men" what caught my attention was when he was explaining his version of the story it went something like "she just asked me if I wanted to get dinner and I said yes" waiiittt I thought you had called me and told me it was work ?? I let it slide. A dinner next to the beach... pricey right? Well he convinced me that work would cover it. (We had stopped going on dates because we wanted to save money) so yesterday we're talking about him grabbing lunch with one his guy employees and I was like... does work cover all this ?? And he was like no , only sometimes if it's during work hours and about work.
