Could this be real love?

I'm very cynical toward love... I've been dating the most amazing man for almost 2 months now, he is literally every thing I have ever wanted in a guy and treats me like a princess! He has been talking about getting married and tells me how much he loves me. I have a total peace in my heart towards him which is weird for me because I never have peace bout anything! As much as it scares me I really can't see my life without him and feel like I really do love this guy... can this be real? Can you really just know you love someone like that? Has this happened to any of you?
