Should I just move on ? By the way I'm new to this so I hope I'm doing this right . (:

So I've known this guy for 11 years and we've always been the best of friends in 2008 we lost touch but in 2009 we started talking again ... Our moms have been best friends for many years . We dated , then broke up because of rumors . We became the closest in 2011 we were most comfortable with each other than we have ever been . I felt like he liked me and everything we would hang out together in school and be in our own little world forgetting everything that's going on . one day he even stared into my eyes for like five minutes . (cheesy I know .) I feel like we can make it work were so much a like and we get each other so much and we both went to each other when we needed someone we talked almost 24/7 . He had givng me his email to check it for him onc in a while because he will send stuff to me to his email , and He was going through a rough time and I happen to see that his girl had messaged him saying a bunch of crap that she told him I had said ... But. Didn't even know her . (they had been friends in the past for about a year and he drifted from her and then dated me , he had told me he doesn't like her at all and that she's annoying . ) he got really mad . I got scared because what she told me he was saying put him in so much danger so I told is mother . Obviously I didn't want him to die ... He was talking about that and this girl I don't know added in all this extra information . So he decided that he doesn't want to speak to me ever again .... Its hard for me because I've been with him through literally everything ... Even when he almost died because of a really bad fever and wouldn stop seizing . And this girl is like now the oly person he talks to and every time she sees me now she will look at me and give me the 'haha I stole hiom from you look ' what should I do ???
