Our parents have been separated ever since I was still young. It has been 14 years since then and it is true that both my mom and dad have been seeing other people. In fact, my mom got married again after five years of separation, this time with a foreign man. Dad, on the other hand, have just been casually dating. It was a problem at first because he brings his girlfriends at home but we just adjusted to it. We never actually thought he would ever want to get married again since his separation with mom because he was only into casual dating. I also don’t think it would be a good idea since his fiancee is just older than me by five years. How do I tell him not to remarry without making him upset?
