<human>: Give me a shortened version of the text

My boyfriend and I have been in a relationship for three months, of which two weeks have been long distance. (He goes to school 1,000 miles away from me.) He doesn't mind me hanging out with my guy friends, but when I did once, I forgot to tell him that this guy who likes me was there. When my boyfriend later found out Guy Who Likes Me was there and I didn't tell him, he got a little frustrated.
Furthermore, we logged onto each other's Facebook today. He was messing around and looked at my messages. One of my messages from a week ago was from a guy who said, "Let me wank on cam for you" and knowing he was probably joking i said "sure". I remembered I had that on there with previous messages of us just having normal conversations and I didn't want my boyfriend to take it the wrong way so I decided to delete the entire conversation while he was logged onto my facebook. He saw the comment from the guy asking to wank on cam, and THEN scrolled up to see that I had deleted the entire conversation from where I sit 1,000 miles away. He doesn't know what we were talking about previously and was really pissed to say the least. 
Now, I have never cheated on him and most of the misconceptions that occur, happen because I have an awkward way about situations like this. We spoke via Skype and right now he's deciding whether or not he trusts me enough to stay in a relationship. This may sound stupid, but I feel helpless and numb and I was just wondering what the fuck I should do, if I should do anything at all.
<bot>: My boyfriend has trust issues with me in our long distance relationship and I have no idea what the fuck I should do to keep him from breaking up with me.
