heart broken and so pissed

so my husband is a part time dj and he asked me to look for some music for a gig he had over the holiday wknd. I 1st got a notification with a girls name from his past attached, which lead me to his email. which lead me to find a whole different set of emails between him and another woman. Now granted these emails were from about a year and a half ago, how very when I asked him about it he lied said it wasn't anything. I then showed him what I found. he was apologetic and said it was in the past and wanted to avoid an argument on out off days together. I'm pissed so pissed that I had to leave for the wknd bc I feared for his safety. anyways just venting. haven't seen or spoken to him since Sunday and idk which way is up. we had just got to a really great place again snow I feel like it's all a lie. to make matters worst during the time period when I found thr messages, I had just MC our twin boys and lost my father which really pissed me off more. thank for listening
