Why disconnect happens?

Why disconnect occurs in a relationship? This question was asked which gave a common answer of expectations but is it only that? I heard multiple ideas from different minds all coming to the solution to some of the experiences they too might have faced. There were many ideas shared like miscommunication, lack of maturity to deal with a situation, lack of listening to the other person and so on were some of the ideas shared by my friends.

I think the disconnect between two people might be because of the comparison between two different individuals. Every individual is different so when a comparison happens gradually the relationship gets strained leading to breakage. The expectations that arise due to comparison put mental pressure on the person pushing them to get exhausted in the relationship. Once exhaustion hits it's a sign of disappearing relationship. 

It's never easy to maintain a relationship but to keep it alive an understanding between two individual needs to be there. Every individual has their own personal space and when that space is respected an understanding between them strengthens. In certain. families the husband and wife even though are in a marital relationship have different career paths and they do not interfere but support each other. This is a healthy relationship that I saw years back after having a short conversation with the couple.

Apart from personal space I believe assumptions should not be there in a relationship. For example, when a problem arises the required individual is to talk to the other person rather than assuming and creating their own scenario. Assumptions lead to overthinking gradually causing a strain on relationship and developing a grudge deep within. Anything harmful when accumulates in the body affects the physical health, similarly any overthinking or negative thoughts emerges it affects the perspective of the person.

Relationships are complicated and difficult to find the balance, but proper communication and genuine interest in the other person breaks the barriers and provides harmony to the relationship .
