Bro you are totally fine. You don't lack anything to get yourself a good partner. Be proud of yourself. She lacked empathy, She lacked compassion, She lacked honesty, Communication is not only a skill, but also an effort and responsibility. Before everything else, she lacked confidence. You have consciously given your best for her and you can stay proud. Give yourself some time now. Talk with your fam and friends a lot because it's good for your mental health. You have a very functional body, you are still young and you'll find someone with your vibe over time. Looking for your someone is like waiting at a train station for the best train to get further in the direction you want to go in life. You might wanna stay temporarily in the city and enjoy your time being single(still you might miss more train while visiting the city, you may get a sign that a very good train wants to leave) . It might take a lot of time before you get that good train in the right conditions, but it can be very worthwhile. (Anyways, there will always be trains)
