should i be mad or sad?

You sound funny,sorry.I know how you feel,although his mom told you that,it is so humiliating , but let that be so. The fact is that you can be mad and sad,too. If you care for him, and if there is a way to talk to him,find him and talk. Find a solution together. If you both decide to break up,then do it. You are still young,you'll find some other love.Otherwise, you can make the things between you better,and to stay together. However, i wish you all the best.
