Second boyfriend? Didn't work. Took me about a week?
Third: Really liked him, but he was an ass. Took me about a week, too.
Fourth? Over him before we even broke up.
The list goes on.
While still getting over my first boyfriend, there were a few guys that were quite interested in me. I didn't even care. I was still attached to my first boyfriend, yes.
I honestly have asked myself if I could ever feel what I felt with my first boyfriend again. I personally once you fall really hard, and the breakup is devastating, it will be hard for you to love again. Deep down in your brain, you're afraid of that devastating breakup.
I do NOT let myself fall easily anymore. I'm extremely cautious. I am not friends with any of my ex's (Which is probably a good thing).
