sexting

I caught my boyfriend sexting other women after looking thru his phone and he was asleep...by looking thru the texts I saw dick pics , how he wanted to do things and etc. it even sound like he actually acted on these things....once he realized I found out he was confused a lil but then realized what I have knowledge of he didn't really explain to me who the females where or what the intent was but he made sure to let me know he didn't act on anything and it was all entertainment ....what should I do next he wanted to be with me and make it work???  Answers 😩😩🤔
