sub17, you are not a bad submissive. Go look at yourself in the mirror and tell yourself that.
Everyone once in a while we have to take a step back and remember that we are not only submissives.... we are also mothers, daughters, sisters, friends, employees, co-workers, etc. There will always be times when our other roles have to take precedence over our D/s one. If only for a little while.
You are both about to make some serious changes in your lives. You are moving, which is always stressful, but if you are moving to be with him, this is also a big commitment for both of you. It is completely understandable if you are both on edge.
Now, more then ever, you need to communicate and attempt to understand each other. The transitions you are about to make will not always be easy... and you must work at turning towards each other, and not away.
I wish you both all the best...
