Is it naturally to feel a little worried about moving in with my partner?

First try to make him as happy as ever and don't get to boring like talk to him and every once in a while go out and keep the relationship going and move in all your stuff, that's your home now. Keep you boyfriend interested in you and he won't dump you so move in all your stuff to give it a homey touch. Hope this helped. Btw if you get him bored he might start wanting to see other people.
