Be aware, pay attention to how people treat you.
One of the most confusing and damaging ways abusive people cause harm to you is by "love bombing." Confusing because it's the direct opposite of the hateful way they have treated you, and damaging because they "love bomb" you to purposefully confuse and manipulate you into staying put so they can continue to take from you what they want. People who want to cause you pain and harm will never really have love in their heart for you. Love bombing is not love. It is insurance for the abuser to keep you in your place. Recognizing it for what it is is crucial in showing yourself respect of your worth, and realizing you need to get far, far away from this person. I know this tactic very well because I lived with it for years. I didn't know it was a tactic until years later, well after that relationship had ended, and then I was slapped with the realization that much of my relationship was the push and pull of abuse and love bombing.
Love yourself first. So much that it is beneath you to accept less.
"Love bombing is an attempt to cover up mistreatment, disrespect and or betrayal by showering a person with forced affection and attention. This can be used to confuse you and manipulate you into providing second chances to people who in fact intended to hurt you. Be careful." - r. h. sin
