2nd Chances

Recently my boyfriend of 3 years I discovered was sexting and sending pictures to another girl. I don't know if I can forgive him. I love him so much, like even after I found out I just wanted to hug him, because he's the only place I felt at ease. It's hard to move on cause he says it was just that girl, and that I was partially to blame because I was never around (I work 65 hour weeks). I just feel like I can't tell if he's being honest about that with me. I do everything for him and feel like this was a slap in the face and that everything I do is taken for granted. So. 2nd chances. Is this something we can work through? Because I can't think of anyone else I want to be with.
