<human>: Hi! It's my first time writing here, so I hope u can give me some good advices!

I'm so desperate and needing help! My 3yrs boyfriend told me last Tuesday that he cheated on me while his was traveling abroad last month. At first, he was so ashamed that he couldn't even look at me. He told me late at night, so he said we could talk in the morning. We did talk the other day, but he was so confused and upset to himself, that didn't know what to do! I'm couldn't have no sleep in the first day I got the bad news.. I was so angry, feeling stupid for trust him so much... I kept thinking what we should do, and decided to give him another chance, because we were SO perfect together, never had a fight, both our families and friends loved us and he told me the truth...
But when we talked on the next day, he said he didn't know why he did it. And don't know how he feels about me!!!! How is that possible!? He was sure that he loved me before the trip, and when he got back, he's in crisis?? He told me he knew he loved me, but maybe he din't love so much, or else he wouldn't do it. How can someone love another, but not THAT much?? I always though we LOVE or DO NOT LOVE. :/ I told him we could try to fix things, I was terrible mad, but I still love him SO much, and want him in my life. I gave him time to think till monday... but I'm scared of what's going to happen. Never passed through this before, and never loved someone so much in my life!!! I really don't want to lost him for some stupid mistake that he confessed me and already regretted. I know I give him time till monday, and I'm trying my best to hold myself and don't call him... Do you think it's possible for us to be together despite of what happened?? Any of you passed through something similar? Need advices!! I'm so scared!!! (I'm barely sleeping, lost my appetite and can't stop thinking about it! :( )

Can you provide a brief overview of the text?
