Trust is the foundation.
Love is great, but never prioritize it over your own life. It has to be self-growth or attachment cause so much issues. If you told him that you may not be available much, that's good. He has to learn that too, that he must do things for himself, and sometimes for you too, but never for you only.
I believe you 2 can grow stronger bonds, if you manage to handle conflicts and pressure correctly.
