What's wrong with me?

For the last week or so, I have been so busy with school and work and everything but no matter how many things I have to do, I still can't stop thinking about my x. I tried. I tried everything and it does work and it does help but it doesn't make it god away. Yesterday it was so beautiful outside and as I was driving and looking at the city, I started remembering all the good memories we had together. There were so many...going to the lake....going to the aquarium...running in the rain...the sprinklers going on and getting us all wet while sitting outside...going to the movies....dinner... of course there are specific details about those memories that make them so hard to remember. I got all sad but then I realized that whenever your heart takes over your mind, you just have to remind yourself that they let you go. Maybe they are not even thinking of all those good times, or what they are missing out on....maybe they really are jerks and are rebounding with some other girl.
Truth is that boys and girls are very different. When a guy says he is not ready for a relationship and then comes back a few months later begging for attention again, girls make a list of why he was right...he was busy with work, he was stressed, he had so many family issues... etc. ...whatever the case might be. Guys, on the other hand, will just say you lost your chance, you walked away. This is why things for guys are so much more simply. They don't start making excuses. They make a decision and stick to it. That's what we all have to do. It's so easy to fall back into the same old trend, especially if they are making a big effort to get you back but just remember that they were the ones letting you go, so don't waste your time making the same mistake. Change takes time.... a long time...don't believe them if they come back after a month saying "they realized how important you were to them." It's what you want to believe, it's what you wanted them to realize but most of the time that is so short lived. Have the courage to stand up for yourself and be strong. Always let your mind be on top of your heart..... only when you find someone who respects you and knows you are what you want allow your heart to be above your mind.... just a thought....
