Relationship Question/Need Advice?

So there is this girl that I've been talking to for a pretty long time now and we're a couple now. We're both young but this is my ';real'; relationship and I'm a little weird on handling it due to my inexperience. She's been in a few serious relationships throughout the past few years and she's feeling that she is ';in love with me';. Since this is my first ';real'; relationship i'm not really sure what I feel. I know i love her to death but as far as ';in love'; with her I have no idea because I've never been this far in a relationship before and i'm a little scared on how to handle it. We both have plenty in common, and I get that ';spark'; when i'm with her, and we click pretty well besides some of our taste in music such as my true passion for hip hop, and I'm worried that if i find someone who shares this same passion for my music and some other things that I won't feel the same way about my girlfriend......What do i do?Relationship Question/Need Advice?
you be yourself. n also with love. u dnt have to have everything in common. You can have similarities and differences. be yourself n the rest will handle itself. if she likes you for who u truly are and you feel the same way about her everything should work out
