Serious abandonment issues..?

you should go talk to a psychologist. It could be that things are going good and subconsciously your afraid things will turn bad or subconsciously you are afraid that your BF might leave like your father. If could be you have grown co-dependant toward your BF or it could be seperation anxiety. Really it's hard to tell without knowing your life story and that's something to share with your psychologist. Then again it could just be a hormonal holiday thing.
