Your cake sounds yummy! The occasional cake doesn't harm, the daily one does. Have fun with your light, dancing to it will be fun! Small losses are better than gains. Keep on doing the best for your life!
I hope that you can figure out what Mike's issues with the move may be so that he can cope better than drinking. If it doesn't stop, perhaps going to some counseling sessions, whether together or by yourself will help? There might be some depression because of the move. This number may help if you don't see a way past this bump too: 1-800-273-TALK (8255), I haven't had to call yet, but Facebook God has and said it helped in a crisis.
Do you have a JoAnn Fabrics or Michael's nearby? I took my cake classes at Michael's for a fair price. Having an oven that heats right helps with baking the cakes. It takes practice, but if you can do muffins (which are basically naked cupcakes), you should be able to do cakes fine. :)
Good luck selling the house! I hope it goes quickly for the price you're asking. Living in an apartment isn't all bad, I've been living in one for years now.
