Why a lot of my friends ask if you are single?

Most of my friends are guys, because it’s not many girls in my circles. But since i have boyfriend, i respect my boyfriend, so i avoid to hangout with them in the night. Morning and in the day for a coffee or lunch is fine.
But some of them asked me the same question every time i met them.
“Are u single now?”.
That’s really bother me, I think that they hope i will be dumped someday.
Should i cut contact with them?
