It's nice to remember back to a more simple time in life. Remember when you weren't afraid to love? That was a good time. It was so much easier before to let someone in with no second guesses. It used to be all day communication and cute little texts. It used to be hanging out until three in the morning, couldn't let each other go. Back in those days you couldn't wait to see that person. You simply fell and they caught you. It was easy.
Unfortunately, for whatever reason, things fell apart. It doesn't mean this person did anything malicious, sometimes life gets in the way. Suddenly this person you gave your whole self to is gone. This is where you had to pick up the pieces and try to move on. It's normal to look back and think you were being naive. You weren't. You just let someone else have you. Sometimes people don't always mean what they say and that's one of the harshest realities we have to face.
This isn't a sappy letter to the ex love you once had, this is a letter to ensure that it's okay to not love like that.
There's a different and better love out there and you will understand once it comes. Don't ever forget you are the only one who will always have your back. Make sure you don't give you entire being to another person because they may let you down and then you will be lost. Maybe that puppy love isn't the type of love you need. Maybe a more mature love is in your near future. Don't ever lose yourself in someone else.
