Calm down and think about why you can't find someone. The main reason for many older unmarried women nowadays is that they have no social circle. So don't always stay at home at two o'clock and one line at ordinary times, let yourself communicate more and go out to play more, so that you can meet new boys and maybe there will be someone suitable for you.
Another conservative method is blind date. Don't think this is old-fashioned. Nearly half of the young couples around me know each other in this way. Let your parents, relatives and friends pay more attention to whether there are suitable candidates, and see more and more contacts. Even if you don't feel anything on the first side, if you don't dislike it, then the feeling may come. Don't always list so many rules for yourself, everything goes with the flow.
In short, there is no girl who can't get married. As long as you want to find it, you will meet the right person.
