You are pretty much dead on! Yes I do this in a lot of my relationships...which I usually regret, but during the relationship I am caught in the moment!
I've read the signs for commitment Phobia - I've read Kiss and Run - and BPD and I am reading "Get me out of Here" - I seem to have a lot of symptoms for both! It is scary.
I have only recently accepted that there is an issue... this is new to me. As of now, I cannot afford a therapist - I am a single mom! However, in the future, if I can... I think you're right - it would be beneficial.
Thank you for your comment... It is nice to hear other people's opinions and advice
