Cheated...

Yesterday my boyfriend came round who I've been with for over a year... He looked at my phone and saw hot or not and that I've been talking to guys and I sent one guy a inappropriate photo.  I felt so bad about what I've done, but I still Iove him... He still wants to be with me but he wants to take some time apart. How do I make him hurt less? Cause I'm hurting knowing I've broken what him and I have built....
