How do you get past the fear of falling for the wrong person?

Growing up, I had a lot of self esteem issues. I was not the most physically appealing because I didn't like myself enough to treat myself with respect; I did not take care of myself. I was extremely introverted and felt like I had to fit in. Because I was so needy about it, I was super awkward and uncomfortable so I had difficulty making friends. Also, my home was not exactly a safe haven, at the time. Because I kept failing, I stopped trying to make friends and eventually found comfort in solitude. I had to work a lot on myself to get myself out of that dark place and I developed self confidence. But any time I think of dating or being in a relationship, I feel uneasy. I realized it is because I worked so hard on myself to develop self confidence and hold my head high. But I am afraid if I end up in a toxic relationship, I will revert back to who I was prior. I am afraid I will become jaded or will be unable to walk away from a toxic situation and all of my hard work on myself will be thrown away for a guy who treats me like trash. Is there any way to get past this fear?
