None steps into a relationship knowing how to be a healthy partner, we go through life knowing about it from our parents, our parent's friends and movies or novels. I never met a healthy love relationship while I was growing up. All my partners came with a heavy backpack from their own family scars. You learn between the process. Sometimes you find someone who wants to work out in the relationship to become healthier together and sometimes you have to part ways because you realize that you have been hurting all the time. And each time you learn a bit more about yourself, identify the toxic habits that you gave as normal and try to change some habits that don't make you happy. It's never easy to realize the person that you love is hurting you and find the courage to move on and give up on all your hopes and illusions. It breaks your heart every time. And you can't remain friends with someone who you loved so passionating or that you have so toxic behaviours because you never choose them as friends in the first point, you choose them as lovers.
