When this happens (IMHO) it is a person having a superiority complex and then realizing it is a friend they love and care for trying to direct that angst into something usable by trying to help in the wrong way.
It happens with men to women in hetero-relationships all the time … I don’t want you to fix my problem but help listen to my problems and if I ask for help then you can fix.
In the 1990’s I had a running joke … it was the happiness glass of life. We all live happy young and free …. folks that are older and more experienced see this and become jealous. So they stated you know what could help you fill your happiness glass …. a partner …. it then gets filled up and then drained lower …. (life you know)
Then as time goes by …. you know what would make you and your partner more happy ….. marriage …. (glass water goes up … and then gets drained lower then before)
Then … they state …. children … that will help … (repeat)
Then they state you are so miserable …. divorce … (repeat)
Then … this ….
The solution … don’t listen to other’s prescriptions of how to make you happy.
Now if they are nervous about your single-ness … it maybe because they are projecting …..
