Is this love?

Okay,

This is a long and  confusing story. My sophomore year of high school, I met a girl. To prevent confusions, we will call her "blondie #1". I began to lust after her a few months into our friendship. I eventually shared with her how i felt, which she didn't take well. She was an amazing friend, however, and even thought it was creeping her out at the time, she was there for me. Eventually, she developed similar feelings for me and we decided that we would experiment with each other to see how it was. (That "experimentation" is still going on now... three years later, just so that you get the hint of how it went.) My mom quickly learned of this, by reading a MySpace message that I sent her and attempted to end our friendship, which I didn't let happen. During senior year, our  friendship fell apart because she wasn't being a good friend. She left school unannounced because she couldn't handle me becoming best friends with her enemy, which we shall call "blondie #2". Throughout the school year, i attempted to contact her but never got anything back. && drove myself crazy, wondering where she was, and even breaking into the school's student records to get information. Finally, when i threatened to show up at her house, she responded. We talked during late nights, when she finally explained things to me. Communication was rare for the remained of the year. On Graduation day, i was very disappointed that she didn't show up. But her name was on the graduating list. Over that summer, i knew she had gone off to college. I stayed in our home town, and became even closer to Blondie #2. I ended up falling in love with her, in a way that i had never felt before. My mom kicked me out of the house when she learned of this second relationship. I lived with her for about 2 weeks before mom asked me to return home. Anyways, the day after I had ran away from home, i learned that Blondie #1 was in town, had showed up at my house to talk and learned that i ran away. She contacted me over Facebook and we argued because I told her that I wasn't going to leave the Blondie #2. This was in October 2010. On Christmas, i texted her and wished her a Merry Christmas. I had spend the past 2 years worth of holidays with her, and it felt wrong that year without here. This ultimately rekindled our friendship/romance. My relationship and friendship with Blondie #2 ended when I let her back into my life. She (blondie #1) was there during the down-fall and conclusion of Blondie #2, like a great friend. The year progressed and we attempted to have a relationship again, and after 3 months, she dumped me over facebook drama. She tried to take it back and fix everything but I wasn't having it. Since then, we still fool around and are very protective of each other... But there's no "relationship". (This is the same game that Blondie #2 played with me for months!) This weekend, we had a date. She took me to dinner and to see Breaking Dawn. She bought me my favorite drink (that i'm not allowed to have) and took me to my favorite pizza place, then took me to see the movie i had been dieing to see! We held hands throughout the movie, and made out in the car before dropping me off at home. The next day, i spoke to a friend who gave me encouraging words. I was contemplating on a "relationship" with her again, but i wanted something more meaningful, more stable than just "going out". I wanted her to tell her parents. Her parents still refuse to forgive me for the whole Senior Year thing; and even though they know about me and her in the past, they think it was all me playing with her mind and don't know she was a willing participant. Well, she's scared to tell her parents because they won't approve. Her sister doesn't know either. Anyways... what I ask is this: Is it wrong of me for being discouraged about our "relationship" because of her fear of telling her parents? And secondly, is this love? I'm young (only 19) and i'm not quite sure what I feel for her. It's not what I felt for Blondie #2; but i cannot be without her. We've been through ups and downs, and i've never stuck to someone's side as much as I have hers. Regardless, I still feel like I dont know what I'm feeling for her. Someone help me, please.
