Partner works from home, I came back and found him masturbating talking to his boss on the phone. He quickly shut the door and said he was doing work stuff.
I couldn’t hear for a few seconds because the drier was on. It didn’t hear like anything was going on.
Then a few seconds later after I confronted him, I heard work talk going on. I turned the drier off, and he told me to turn it back on.
I confronted it about it and he said he had work calls to make. He said he was masturbating and then she called. He continued to do so while on the phone with her. He denies having a sexual relationship with her, attraction or phone sex (currently on present), he said he gets horny and masturbates a couple times a day.
I looked at his phone and it doesn’t appear to be a video chat. It looked like a phone call and he could have deleted it.
He was dismissive about the whole thing, and trying to tell me he was embarrassed and didn’t want to talk about it
I told him that doesn’t make him look good. He said I’ve been faithful for your for 8 years and I’ve never cheated on you. He got special permission for a remote job. And now I’m wondering if it was because there was an affair.
What should I do?
TL;DR boyfriend on the phone masturbating with his boss, while stating he had a regular work conversation. He stated he is not cheating, he just gets horny multiple times a day and does so even when he is talking to other coworkers. I don’t want to throw away 7 years.
