i would divorce her and take everything. fuck her and the baby. id also get a dna test on the baby. if its not mine, id never see it again in my life. my brother, depends. it would have to be a physically painful, tactical revenge. i would have to wait a few years. let everything blow over. let the fly stick to the web, when ready, bring the pain to him and his family. then i would leave the country forever. hypothetically of course.
