It can also be applied to any gender however I'm gonna write in girl's POV. Assume that this is vice versa

Words are dangerous because some are too good that turn out to be lies while some are sharper than swords, and hotter than burning furnace.

We must be careful being swayed with words. Most boys knew how to gaslight and still have the audacity to be mad at you when you react. Let's be careful and don't trust anyone easily. Be careful with yourself.

Do not ignore any red flag as it will be the same reason why you're breaking apart.

Promises shoot our hearts

All the promises and all the stated words that we always dream to hear but turned out to have expiration date. They just want the initial phase of relationship, the excitement, sparks, butterflies, and rainbows. They put efforts to get us then when they already got what they want they'll start changing.

Let's not rush in relationships. Know each other well. Observe how he act when he's happy, sad, scared, mad, in every emotion he has. As well as how he behave with and without you. Give yourself time to see each other's true color.

In this way we'll not cause another traumas that may cost and last a lifetime.

Align your words with your actions

This is the most attractive behaviour a man can have for me. It's not easy to be consistent but a never ending will of trying to be better or at least maintain the characters you have at the same time at courting stage...this is real.

However, be careful again as some can pretend for a long time because they also fooled themselves.

Have courage to walk away

Women don't walk away easily. She fought, she drained herself, she gave everything she can do to save the relationship and to love her partner. That's why it's common that women don't regret the break up.

If there's no character development then leave. You're not there to fix him, you are there for each other to grow and love then naturally be happy. However, if the toxicity is kept on cycle, when you try to address issue but always seen as seeking for arguments, when you become dramatic and pathetic to his eyes because of his own doing...sighs. Don't settle for less

Sometimes it's best to leave it all broken than to hurt yourself

I know that it's sad to say goodbye to the person you wish to spend your lifetime with. However, think for yourself. Try to think about what family you can have with him being like that. Go where you're treated the way you deserve.

Let go of things that are no longer good for you

You don't need a boy, you also don't need a man. However, you can want a man. Settle for what's good for you, to that one man that never find it hard to give bare minimum or even go beyond that. That one man who can't disrespect you as well as let you go.
