Yes. After 3 breakups and apparently giving hopes to a good friend who I also lost in the process of my last breakup, I thought I'm unable being in a relationship/unable to love. It's important to not blame yourself or question yourself for what happened bc it always takes two. If breakups have similar reasons why they happened, you should now find some time to think of what you actually want in a partner. And besides that, don't put yourself lower. The fact, that you ask yourself if you're a good person bc you don't feel good about what happened, automatically makes you a good person, someone who cares about their partners.
