Do you have sisters or any female family members? How do you deal with them, if you have them (other than your Mother of course)...

There can be a sliding scale for therapists, or even a help center may be beneficial. We do have the ask a therapist option also here...

To me, if you say "you know what is going to happen," you are already setting yourself up for failure or for the girl to dump you...could you try and work through the negative thinking?
