Online dating destination match.com suggests ways to meet new people:

Online dating: Break free from your friends more subtly and join a dating site. Then you are not physically turning your back on them or abandoning them on a night out which they might take offence to.

Social event: Attend such events and meet other like-minded people. Your friends might have the same opinions as you on a lot of things but they might not be in the same place when it comes to dating.

Take friends along: When you go for social events, take your friends too. Then you can all mingle and extend your social circle. You might even find the one.
