So I met this girl that I really like talking to and doing things with, it's almost gotten to the point where I can't stop thinking about her and how alive she makes me feel. I'm not sure if this is love or what so can anyone tell me signs of being in love? I'm not completely sure if what it is I'm feeling is that.

Love is nothing others can tell you.
Dont get strung up on the term or others definition of love.
If youre unsure just try spending more time with her.
