Sarkis says there are several stages to gaslighting.
It happens gradually over time, so it can be difficult for the victim to identify before it's too late.
They probably told you how different you were to anyone else they've dated, how you were "the one," and you two were "meant to be." They might have complimented you all the time, given you expensive gifts, even taken you on holiday.
In reality, they probably weren't Prince/Princess Charming at all, they were just reeling you in, psychologists say.
It has to be someone who they know they can get a lot from, but also with vulnerabilities, according to a blog by therapist Silvia Horvath on Psych Central, which is why they often target people with low confidence and an underlying self-esteem problem.
However, the mark is also usually a very caring person who is willing to do things for other people, says Horvath, and often they also show passion for their family, friends and career.
This isn't to say what they're saying isn't true, but it's wise to be wary.
It's when someone makes you feel like you're the most important person in the world, and they must be the one for you because they seem so perfect.If you're in a relationship with a narcissist, or someone who you suspect might be a sociopath, it can be difficult to explain what's happening.For example, day-to-day in the relationship you may feel alone but not quite understand why.When they're trying to reel you in, a narcissistic person is likely to mention how badly they've been treated in the past.
They may refer to past abuse in their life, or bad previous relationships.
According to a blog post by psychologist Dr Stephanie Sarkis on Psychology Today, gaslighting is a tactic manipulative people use to gain power over someone else.
