Why is he cheating on her?

Would really love a trade on this tho, so I would really appreciate a querry back.

Pre-natal zhen, post-natal li.

Initially, even though she tried to do her part for the relationship, he wasn’t putting in much effort. This caused the relationship to progressively weaken before he began cheating.
Right now, it might appear that their relationship is strong, but in actuality it is very weak behind whatever facade exists. Even though both of them were putting in effort recently, I honestly don’t believe they were compatible at all. They certainly aren’t any more.
