I broke up with him and idk!!!?

I broke up with my bf Kevin and well I sent him a message thru Facebook cause he got his fone taken but now I feel really kinda guilty and I kinda want him back. But idk I broke up with him because he like never showed any affection to me and we were going out for 2 weeks and he barely hugged me and we had no classes together and I never saw him. Idk if I want him back cause I already started talking to another guy but I feel so guilty! I kinda feel bad and like in the pit of my stomach I feel this weird like churning. I don't know if he read the message yet so I can still fix it but idk if I should. Is it normal to feel this way? Will it fade I just don't know anymore. Please give me honest advice! :(
