Yeaa, I would say focus on your strengths. Its understandable considering, i think you mentioned the person you are with now is your first? First anything is really difficult to  let go and it also makes sense that you feel you’re not sure what to do when developing close relationships with others sometimes.

Practice makes perfect.
