I Regret Being in Relationship

In the past I was in a relationship where I constantly felt like I'm doing something wrong. I didn't feel loved and I did everything I could to make the other person affectionate towards me. I asked a lot of people and googled various questions and came to a conclusion that the other person didn't know how to show affection. I genuinely loved them, hence I didn't want to hear anything negative about them. I thought its okay not to feel loved and continued the relationship for four years with me feeling insecure, unloved and overall disappointed. Then I made the obvious choice to break up. And when I did, I didn't feel sad. I just felt relieved. I thought to myself why didn't I do this before. I was really relaxed after so long. Then I was approached by another person who showered me with lots of affection. I, who had not experienced such affection, loved receiving it. I thought I was in love with them and agreed to be in relationship. Now we're 5 months in relationship, and that person still loves me a lot but, I, slowly started to realise that I used them to fill a void in my heart. I believe I am the worst. I regret being in relationship, I regret that I gave him hope. I want them to be happy. I feel I ruined their first love by giving false hope.
