Getting along better with women, and having an active dating account while supposedly mutually exclusive are two different things.

Even when insecurities arise, its' also important to not invade privacy, not sure if that's how you found out, or if he came clean. And I'm not going to judge here, it happens, right or wrong, it happens.

It's just, that it's more important to be able to sit down and articulate concerns, vulnerabilities, et al, before actually taking such a path. And to articulate, it's real important to understand what needs are and aren't being met in the relationship, that leave one feeling insecure about things. And sometimes, insecurities come from within, so it's important to be able to differentiate between them.

If needs are being met, then it's where trust builds and forms.
