You don't have to google it if you don't know about it. Gaslighting is all about manipulating and trying to make other people feel doubtful about their existence by degrading their self-esteem levels. It is one kind of emotional abuse where it takes time for a person to realize the whole scenario. If your partner is too self-centred, then you may observe these gaslighting behavioural patterns when you start losing yourself. It is toxic for sure and if you are in a relationship with a person who makes you devalue yourself, then you must recognize the whole manipulation in and around you.
Regardless of orientations and identities, many people are narcissistic these days, and even from the queer community, you find way too many homosexual men as typically self-absorbed. It is not a stereotype, but most men tend to display these kinds of behavioural patterns towards their partners especially to prove their points right at any cost, even at the cost of their partner's mental health and emotional stability. But before the confrontation and deciding to step out of the relationship with such people, you need to realize those patterns. And that happens only when you observe changes in yourself.
You feel like sacrificing your individuality and without any knowledge of your own, you may end up depending on your partner's decision on every single perspective of your life and lifestyle.
You invariably end up trying to please your partner by accepting the mistakes you never commit and also you may stop defending yourself even though it isn't your mistake at all.
Surprisingly, you believe every manipulative move of your partner without checking the facts and sometimes you bear the guilt of your partner's mistakes on your shoulders.
Even though you possess all the facts, situations, and truth under your control, you feel like losing all the control when your partner twists the tale by goofing around with you. And before even realizing you end up doubting your integrity and authenticity of the sources from where you get to discover the truths.
You countlessly say sorry all the time without considering the limitations of apologizing for every minute aspect.
You stop prioritizing yourself and start idolizing your partner as your topmost priority even after getting treated no lesser than an emotional slave.
You feel weaker and opposite to your more dynamic, sturdy, and stubborn personality just because your partner manipulates you to believe that your existence doesn't matter the most in front of his/her presence.
You constantly end up feeling over-sensitive and paranoid of speaking anything because you discern that may offend your partner and it may rupture your relationship.
Doubtfully, you check with your partner regarding your every reaction in the mode of not hurting your partner with words.
You unnecessarily praise to keep the romantic spark in your relationship because your egoistic partner develops you do so to feel superior over you.
If you are dominant in every aspect of life in a practical way to spill the competitive spirit, then being the extreme submissive to your partner is a sign of ultimate manipulation in your relationship.
You constantly get accused of no reason. Sometimes, not replying soon because of your exhausting busy schedules makes you a victim of ignoring your partner in the relationship even though your partner knows your timings very well than others.
You encounter lies that are sugar-coated with fake descriptions, but you fall into the consistent dilemma of sorting the true notions of your partners. Simply, you can't make out what's a lie and what's truth.
Deriving conclusions of thinking everything you do goes wrong in your romantic relationship just because your partner makes you feel so is a reliable sign of gaslight behaviour.
On top of everything, your confidence levels stoop down to the core soon after you return home or whenever with your partner, even though you persuade a new client for your company or do something extraordinary with utmost confidence at work.
To summarize, you wouldn't be the same person you used to be with your partner. If you experience this, then you must notice that your partner is manipulating you continuously to look superior over you by inflicting an emotional imbalance in your brain and by making you feel doubtful about your identity, appearance, and everything else you do in your relationship.
Confront the situation and if your partner however doesn't agree with you and feels that you accuse him/her/them unnecessarily, then get rid of that person as soon as possible. That person's existence in your life does no good to you.
