Jump ship, or stay with him? PLEASE HELP!?

If you say you have abandonment issues then that could be the cause of you wanting to leave him. I think you don't want to give yourself over to him as fully as you say you do because deep down you feel like he might leave you. Im not sure how to explain it exactly but your abandonment issues need to be sorted out if you want to have a healthy relationship with him. You obviously love this guy to death, I think you should seek counseling or therapy if you ever want to stand a chance of having a normal relationship....... with anyone.
