My last relationship taught me to stop waiting around for a man to change. As an adult he is who he is already. Stop ignoring all the red flags and signs. Just leave. Waiting around for him to “change” will just hurt you in the end.
If you truly care about someone, show them through your actions, time & understanding. Step out of your comfort zone to meet them where they are. Show loyalty, honesty and trust. Be consistent in your efforts. They shouldn't have to constantly question your feelings for them.
