I agree with thequilteddove as well. But, also why do you make quilts? Think long and hard about this. These folks didn't ask you to make a quilt.
For me, quilting is a creative outlet that I really like because it is also functional. If I am able to put these things that I have created to use for a loved one ... that is icing on the cake. I have to create or something inside me kind of dies.
Once you have answered why you quilt, you may understand better why the quilts line up with bad relationships. It may be that you were trying to create something tangible to "rescue" the relationship long before you consciously recognized the unraveling.
Believe in yourself and that nothing done out of love is ever wasted.
