Am i really in love or just infatuated?

i recently realised that i'm in love with my best friend and have been for sometime. i've talked to her about it but she feels differently and i've been taking it really hard. antway i took someones advice and asked her if we could pretend that nothing was different and carry on like before. i asked her a few hours ago and since ive felt less in love. i dont feel like my life is useless without her anymore. am i just starting to cope or am i getting over an infatuation?
