(((Konfused))) You need to do what you feel is best, but decisions made in the heat of anything (passion, anger, joy) can often be clouded.
I know you're hurt - and you have every right to be angry because you deserve so much better than this - but I would encourage you to get off the roller coaster, take a deep breath, and make sure it's what you really want.
Divorce is a permanent solution to an often temporary problem.
