You have learned a lesson with this person. Don't be so eager to give your heart away. There are going to be others who tell you how wonderful you are, they will groom you and toss you because they genuinely don't know how to care the way YOU want them to. There are lots of people who will gravitate to you because they will see you are young and impressionable. A person can get so hurt and question their self worth and when that happens, it typically means you have been involved with a person who doesn't know how to value and care about others the way you deserve. As you experience life and different people you will find that toxic people can actually be very charismatic and charming and you may even think "found a soul mate". That's what these people WANT you to think, but it's not genuine and it's more about that other person gaining a sense of power when they get control over you.
