Since breaking up with X-BF, I have found myself obsessed with a new crush. Is it just to fill the gap I miss? I know the answer to this question is yes. I was actively pursuing him earlier, adding him as a friend on FB and then calling him. He said he really wanted to talk to me and would call me back, but that was hours ago and I keep obsessing, obsessing, obsessing.. thinking I'm too old or fat for him anyway. Truthfully, we both broke up from a relationship within the past 2 weeks and neither of us need a relationship, but just to be friends. But, my mind is off fantasizing and obsessing all the time.
