Wenever d man wants it d woman will not be in d mood cos she always disagree. Her husband is also not d petting type instead he will start throwing punch at her joints to weaken her to succumb to his rape which always results in minor injuries. 

Now d husband is threatening to marry another wife or better still hook up with a concubine. He even threatened that the next time she will make him force her that that is the day he will start bringing women home to fuck since she has become irresponsible and cant fulfill her marital obligation. He said that he is tired of paying hotel bills so he will be bringing them home since she cant satisfy him. the marriage is just 4 years plus and even when she put to bed the man cant even allow her heal before poncing on her and getting her pregnant again and He does not care about d wife anymore and he comes home late.
