So I hacked my boyfriend's Facebook with my best friend, you know to like make dumb statuses about 'how awesome we are' and whatever. It was stupid. My best friend told me to look at his messages, but I said no because I trust him. But she doesn't, she has guy issues. She looked anyways and we found this conversation. We read through it, and this was the only one like this, and he was calling her hot and rated her a '10'. He said stuff like I wish you didn't live so far away. And I wasn't that mad because the messages were from the summer, when we weren't dating. Then we went up to more recent messages, back in August. (last time they talked) We started dating on Aug 21st, but the message was from August 27th. He called her babe and was calling her so hot. Now, he couldn't have done anything sine this girl lives in a different state, and she added him because she thought he was someone she thought she knew. Anyways, I confronted him about this and he was completely honest about it. He told me that he totally forgot about that and he hasn't talked to her since then & I do believe him. And I made him cry, and I made him feel miserable for like the past week. We hung out and I started to cry and then he started to cry and he said he hates himself for even making me go through this. He wouldn't stop apologizing and kept telling me how ashamed he was and that he'll do anything to keep me& how much he doesn't deserve me. It'll be our 4 month tomorrow. I don't want to breakup with him, I love him a lot.

He was so devastated, but he told me stuff like "I understand if you leave me, but know I'll love you and I'll spend every day trying to making this right again." & " I ****** up the only thing that matters in my life.. having you" & "you have all the right in the world to hate me" & "I have so much regret, im so sorry."

My best friend is no help because she just seems to like, have no advice, ever.

Should I give him a second chance?
