Could you ever forgive your husband for lying for your whole relationship ?

Just found out my husband was lying the whole year and a half we have been together. Caught him talking to over ten women on Snapchat. He says he didn’t “talk” to them like that but he deleted all the messages so I wouldn’t know. He admitted to watching a girl that took half naked pics and jacking off to her on our couch in our new home. I thought we were fine, and that we were ttc, but now I feel like my whole world fell apart. What do you ladies think I should do?
