Is this problem in my relationship fixable?

you need to ask yourself, can i let go of this or am i going to let what happend before hold me back from enjoying being with this person? if no then evry time it comes into your head imagen him holding you and looking after you making sure evrythings ok and see what you see in him now not when you were blinded by love, if no then dont try you'l be wasting your time, best of luck
