Why should you be worried?
Do you feel love in your heart?
Isn't that wonderful enough?
Do you have to "own" your bf?
Why don't you simply trust in God and let him decide?
Worrying is a waste of time. What His plans are will happen anyway "Let Thy will be done" - so why worry about something you cannt change anyway.
Enjoy the time you have with your boyfriend and that will make him feel accepted and at home too. A man will never feel at home and comfortable with a woman that always worries.
A little (genuine) jealousy can be all right, because it shows him that you care for him, but worrying will have the exact opposite effect and will be a huge turn-off.
