Jon Olsen Vs. the World

I know I'm not a regular blogger but occasionally my feelings are overflowing to the point of having to write down some thoughts.

I've been reading a book about a 24 year-old who's struggling to understand relationships and it's hitting a little too close to home. Scott Pilgrim views his life as a videogame. That he has challenges to face that become progressively harder. As he continues, he gains experience and friendship and a more complete life. This metaphor works well enough until it comes to dating. Scott's main love interest presented in the book is Ramona Flowers who is new in town. As Scott falls hopelessly in love with Ramona he has to defeat each of her evil exes (the challenge of overcoming her past). Scott's efforts work for a time but Ramona becomes more and more haunted by her past. She starts to believe herself to be a bad person and decides to leave Scott. Ramona is now revealed to be a runner. Someone who sticks around until she has bad feelings and then she leaves to find something more comfortable and easy.
          This is where I start getting really connected with Scott because I've experienced this and I've had the same attitude as him. I've always believed that if two people love eachother, they should just decide to stay with one another and face down any challenges ahead. For the girl, it seems to be a lot more complicated than this. All the little things have meaning and this seems to mystify most guys. the worst part is that my last dumper told me that it wasn't anything that I did wrong, but that she didn't have the same feeling toward me as I had towards her anymore.
           I've been dumped twice now and each time I felt that I would do anything to make the relationship work and that nothing could stand in our way. Each time the girl pulled away and stopped saying the L-word. Should I be content to wait for a perfect relationship? Do I just need to find a girl who has learned that relationships are messy but are worth fighting for? The scariest question that's coming up is: Will every girl fall out of love with me and then leave me?
