Oliver made the mistake of once again not telling Felicity about things, keeping this kind of secret from her is directly the issue and is what finally broke their relationship.

Why is that so hard to comprehend?

It isn't that Felicity never knew William or anything like that, it is that Oliver, even when under zero obligation to keep things like this a secret from her did so anyways.

TRUST the issue here, and if Oliver can't be trusted to share this type of thing even when he has no reason to keep it a secret that is a major issue in a relationship.
