Ex-girlfriend now she hates me, says I'm bored, tells me to get out, and says I have a little self-esteem as a person.

Always ask her male friends out (preferably married or have a girlfriend) to show your mature and steady side, try to let her know about your changes, reduce the frequency and times you send her messages, and let her be left out by you after getting used to your concern. It's best not to break the jar and fall, and have an affair with friends or women she knows, or she will hate you very much. After snubbing her for about half a month to a month, ask her out. Try to ask her out to dinner after hearing that she is free that day and wait for her to come out downstairs in the office. It's best not to bring flowers, because you're not sure if she has changed anything for you, and then it's your time. Don't speak ill of others, guide them according to the situation. If you are in a restaurant, please drink red wine and get to know the restaurant in advance. You should know a little about wine, but you know nothing. Don't say inappropriate things and don't do indecent actions. For dress, formal dress is the best, and formal dress is one of the most attractive clothes for men. It's best not to say, I did it for you, because of you, how long will it take me, I love you, come back and so on. Send her home after dinner, tell her to have a good rest, and then you can contact her appropriately, but still keep a mature side. After success, avoid showing your true colors, but occasionally coquetry and whispering in your ear will make her inseparable from you. Come on!
