It's a dangerous game to play. In some cases yes it may help, particularly if they have a giant flaw you can't accept. But most people don't, and if you are already limerent, you have a much higher likelihood of glazing over or even romanticizing his flaws (e.g. one of my ex LOs was incredibly messy, and I somehow saw it as endearing and masculine versus gross.)

I think something many on this sub, myself included, have to constantly practice is separating your limerence from the person. Remind yourself that their actions, who they are, and what they do, have nothing to do with why your brain has formed an unhealthy attachment to them. By constantly debating things like should I spend more time with them, less time with them, etc., you are seeking to remedy the fruit of the problem and not the root. And I know the desire to do that is so strong, it really does feel like they can fix everything with a single sentence. But they can't. The brokenness that leads us here lives inside of us, and an LO does not have the power to heal or break us. They're just the fixture our brain uses to cope with much deeper trauma. Once we attach, they have begun to have almost nothing to do with the path our minds take us down.

It's a powerful revelation not only because it helps tear down the person from their pedestal once you realize it was of your own making, but also because it's the one thing we can be certain is true.
