Is it safe to go into a differant relationship? Or im still in love?

I use to love this girl so much and i was really clingy and wanted her to be mine or no one elses and she doesn't feel the same.. time passed and it fades but sometimes. my heart beats when she messages or sometimes i miss some days and i feel lots of energy inside when she talks. but i couldn't care less if she got married and i don't even want her coz we aren't compatible.
