Sometimes love just doesn't work out. And it's okay. (Some of us who have been single for a really long time are becoming experts on being single!) Sometimes it's not that you don't have chemistry, it's not that you don't have things in common, or that you don't actually like hanging out with one another or have fun together. Sometimes it's just not there, and it's okay. Sometimes it's just the wrong hand in glove.
500 Days of Summer is not necessarily a movie I would recommend, there are sketchy moments in it, but it was a really good look at the struggles of being single and the magic of falling in love. Tom falls in love with Summer and it is magical, for him, but not for her. In the end, on day 500 of their relationship, she has married someone else and he can't understand it. He calls her out on how she always just wanted to be friends and never wanted a "real" relationship with him, and didn't beleive in love. She says he was right - right about love and relationships and right about marriage - just not right about her.
On day 500 Tom goes to a job interview and meets a new girl, Autumn, and he decides it's not fate the guides relationships, not the cosmos that necessarily drop the right person right at your feet, but taking advantage of good opportunities for love when they come. He gets her number and the rest is up to the viewers' imagination.
What I got out of the movie? Catharsis I guess. You move on from broken relationships and heal. Don't lose faith in the possibility love will come your way. And take advantage of opportunities for love. And I'm hoping for my day 500 - let's hope it comes in 2010. Maybe like for Summer in the movie: I will be reading in a cafe and he will come up and comment on what I'm reading and then he'll be my husband! :D
