Hi Maya,
No one is perfect. As you have admitted, neither are you. People will always have flaws. Even those you meet or date online. They are human beings after all. If there are a core set of principles or qualities that you are looking for in a person, be sure to emphasize them in your bio.
Yes, it will take some weeding out and you have to be patient. But, many people have found successful relationships online. You just have to be aware of when you are dealing with someone who is most likely going to ghost on you.
Normally, you will see the signs beforehand. They may not respond to you but for every so many days or they may lose track of the conversation that you were both having and confuse it with something else.
This is often a person who is talking to so many people on the dating site that they have lost track of their conversations. Early signs like this are a warning that you are dealing with someone who will most likely ghost you.
