I'm single. I will find next month 30 and the kinship constantly ask for children + girlfriend. I sometimes annoyed it. I am fine. I have a job and good friends. I really do not really do not really desire for a woman.
I understand! I will also be in January 29 and I'm addressed to children. Annoy right.
Either tell them that you have not found the right woman yet.
If you do not want to say that just that you are happy as it's now and that you should leave you alone.
Then just say that!
Nobody "must" have a partnership or start a family just because he will be 30.
