Got this question from girls network. One of the avid members of this site asked this intriguing question that made me wonder also. Why men disappear?
In my opinion they disappear when they need space from their partner especially when they do have fight and misunderstanding and fall out of love too. But it does not only happen to men, women also do. Most of the time men are less expressive and are not that grown up to tell their partners when they don't want to be in the relationship anymore. So oftentimes to save their face and avoid confrontation they would rather disappear and never talked to their partner.
Unlike women, they want to talk about the issue and find ways to resolve the matter. Making women to be braver than men when it comes to emotional issues.
