I don't understand what is weird in it.. People just tend to be in love, and if their husband or wife cannot evoke their love, they will love someone else..it is just completelly normal, I would assume.
if you're in it, might as well try to make it work.
Yes BUT... In a forced marriage there is resistance from one or both parties, they obviously find something UNDESIRABLE about the other person that makes them NOT want to marry them, so it's NOT like a situation where u have NO OBJECTIONS against the other individual bcos u don't mind them. Where there is reluctance, I wouldn't expect someone to easily fall in love, but I do know it happens, but I don't know why.
