I'm really confused about how i feel. I cuddled up and slept (not ) with this girl (out of platonic love)?

Love isn't always about . I actually think you should be able to talk to someone first and feel comfortable with someone first before you actually consider them as someone you want to marry. She seems like she is meant for you. Don't know how long you two have been seeing each other though. This could just be infatuation... a crush.
