How to get a partner?

Hi. I'm asking totally serious. How you get your "other half"? I seriously need to find a boyfriend. I been alone for a really long time and I don't know even how I should start? I literally have no close friends so nobody can help me meet someone new. And unfortunately I'm shy at first with the strangers. Maybe someone can recommend me some ways or trusted apps (I'm fine with international relationship) to finally find a guy and start a happy family. You can tell me about your experience! Thanks a lot
