I like him a lot but I dont really know him I want him to like me 2

This boy I really like and its weird that I like because I dont know that much about him but I really reaally like him I’ve friggin cried over him. But I dk if ill evn see him again because he keeps movin and all I want is for him to feel the same and to see him again I was tryna forget him but he added a new pic on m.s so I went to looka at it because hes gorgeous -but theres more than to me likin him I don’t know what but I wouldnt crya ova a cute boy-and it brought all the feelings back. How do I get over him if I dont want to I want to like him but I think I should have forgotten about him by now. Sshould I have evn tho I really like him? Im always thinkin about him everytime I close my eyes I see him I just want him too like me so badly and sum peopl say he did/does evn his best friend was like maybe hell go out wit you if you just tell him you like him but when I got the courage it was summer and I cant see him so I mssg him on m.s no response tho then later I found out he and his ex got back to gether before I mssg him and felt so stupid. But it makes me so friigin mad because she friggin asked him out on his 2nd of school and uuugghhh I want to see him and tell him how I feel so badly but I cant what should I do?
