I have just learnt from a previous relationship that if one person in the partnership lacks in self confidence/self esteem that the relationship is likely to become dysfunctional or maybe abusive.

In my experience the person with the low self-esteem/confidence resents and feels threatened by anything that their partner is good at which is not about themselves.

The partner with the lower self esteem/confidence is likely to be cohersive, manipulative, and controlling in an attempt to boost their own ego by attempting to cause their partner to feel worthless and unloved without that abusive partner being there.

That is why it is VERY important that in a relationship you both have an equal level of self esteem and self confidence.

50% agreed & 50% d-agree

Because each person has different likes an dislikes an way of thinking..
It need to be balanced true, but sometimes in some stuffs one behaviour is imbalanced but second takes it positively balancing an understandly..

Do not agree. Some may express their low levels of self-worth with manipulation etc., but it often manifests itself in the opposite: being walked all over, having problems establishing boundaries and speaking up for themselves, being shy and introverted, speaking and thinking negative about themselves etc.

Yes SparklingCrystal I understand and accept what you have written.

So, in a relationship it is VERY important to set boundaries.
To communicate with eachother what you do and do not expect from the relationship.
To be able to discuss any issues that may arise.

Communication is "key" in any relationship.
If either or both persons refuse to communicate in an adult manner, then that is going to be the end.
Both persons should ideally behave and interact with eachother in the adult mindset.

I agree in terms of having made the same experience with my ex wife. Not going into details though. I am glad, it's over, and that's all that counts.

Totally agree, always set boundaries. Communication is very important. Low confidence can be build up if each other communicate well what they need. Without communication, hard to survive in a fragile relationship. Low esteem might not an issue to break up but lack of communication will be a main reason....

Yes, it works both ways, making a broad sweeping claim that a lack of either will result in "dysfunction" or "abuse" is ridiculous in my opinion.

I'm just going to agree with you and call it a day.
