I somewhat agree but it depends. In my current relationship we sometimes argue and rarely we even fight but it's because we truly care for each other. I know this man loves me and would take a bullet for me. (I'd do the same.)
In my previous relationship my partner and me would almost never argue but I was miserable because that person would never want to solve anything.
Now with my current one I bicker, I play I argue and it's the healthiest relationship I've ever had.
Please, don't just give an advice to break up under a post that is about venting. You don't know this person (I don't either.) It's insensitive to immediately jump to the worst possible conclusion and tell them to potentiality ruin their love life.
I've seen too many people break up over dumb things and then be miserable for years because they lost their soulmate... A break up can be a remedy but it can also be the nail in someone's coffin.
Soulmates are a matter of personal belief and not scientifically provable. If you actually cared to analyze my very generic advice you would note that I stated, if he is disregarding their feelings he isn’t the one. If is a possibility, I am not saying that is the case. My advice is IF THAT WERE THE CASE, then they shouldn’t be in the relationship.
If you are miserable in a relationship, you should not be in that relationship. This applies to friends as well. Not just romantic relationships.
Your case about never arguing in an of itself is a problem regarding communication. Bottling up problems, DISREGARDING THEM, leads to nowhere. Cause that is what your ex was doing, he was disregarding your feelings by not talking things out. He probably didn’t want to argue. Dismissing shit just leads to more shit. Which is why I agreed with another user about a little bit of arguing is healthy. Constant arguing is not. People in relationships need to communicate not have screaming matches over insignificant things 24/7.
And I stand with, if a person is being disregarded in their relationship by their partner, then their partner isn’t the one. That means they tried communicating with their partner and they were dismissed, constantly. If someone is not showing interest in communicating, or improving, then they are not emotionally mature or capable of being in a relationship as of that moment.
People have a few options, talk it out or break up. It’s that easy. The over complications come about from the goo goo love mindset they tend to be in which impedes them from ANALYZING LOGICALLY. Now, whether they break up for good or get back together is a different issue. Separation can be helpful. Be it with showing they care enough to change or realizing they are better off without each other.
ALSO, you mentioning how this can kill a person, absolutely wild cause guess what, a person who is extremely emotionally dependent on their partner, should not be in a relationship. They need to work on themselves and seek physiological aide. A person can be emotionally vulnerable with a partner, that is fine, that is healthy but if it’s to the point that their very existence is why they live and so forth, they need therapy. It is NOT HEALTHY to be obsessed with someone, especially to the point of offing themselves over a breakup.
