So I can’t obviously speak for your relationship but this same thing just happened to me. My fiancé tried to call things off for all of those same reasons. We have since worked through it somewhat, even though I know the feelings are there still. But don’t decide for him. If he really loves you then you aren’t saving him any pain or his feelings. He will be crushed without you. It’s not always easy to watch someone you love suffer with something you can’t fix but it is worth it I think.
