Reddit users shared their experiences, recounting the "red flags" they once ignored and deeply regretted. Some signs of a partner's behavior can indicate toxicity and a negative character, but not everyone can recognize them in time. 

The first sign - "Mom cleaned up after me." A girl shared a story where she ignored the fact that her partner was used to his mother always cleaning up after him. This indicated his inability to live independently, but she didn't pay attention to it, only recognizing the "red flag" too late. Now, this guy is her ex.

The second sign - "It's all your fault." A man noticed that his partner never apologized and always blamed him for everything. Such relationships are challenging to call harmonious because the partner constantly has to take the blame or engage in arguments, making it seem like he's at fault.

The third sign - "I cheated on everyone, but not on you." A girl ignored her lover's words about his past infidelity in previous relationships. She believed that she could lead him out of this stereotype, but it ended with the same "standard scenario."

The fourth sign - "He's rude to everyone, but not to me." If a partner shows excessive rudeness to his mother, sister, or the surrounding women, it should be a warning; he may be rude to you too. Initially, he may treat you differently than others, perhaps making you feel special. But consider how long a person can hide their true character.

The fifth sign - "Everyone is bad, and I'm good." If a partner constantly complains about the world, it's worth thinking whether this is a "red flag." Consider how much time it will take before you and your actions join his list of grievances, and whether you're ready to be with someone who only knows how to complain.

These stories serve as a reminder that it's important to pay close attention to a partner's behavior and timely react to "red flags" to avoid toxic relationships.
