Cheating

My husband left his phone at home tonight and I just felt the urge to go thru it. I know it’s not right to snoop but we’ve had issues in the past before we got married and I thought they had been resolved but I was wrong. Last month I left on a Saturday morning and stayed the night at a rodeo to come home Sunday. Sunday my husband should have been at work. According to his messages he sent 5 different women one was his ex telling them he played hookie from work to go to this all day spa and was talking about being naked and they should come. So not only is it wrong he’s messaging other women about coming to a spa, he also lied about being at work which he’s a firefighter. So where the hell did he or who he stay the night with because he sure as hell dint come home to me! Then I’m going thru his pictures and there’s 4 pictures of this girls tits and then one of her fingering herself. So not only now do I not trust him after us trying for 3 months to get pregnant I just found out I’m 5 weeks pregnant. Wth do I do now?! I don’t trust him and I don’t want to be with someone who’s broken our vows and has repeatedly made mistakes. I can’t believe this right now.
