I try not to focus on that anymore cos happiness has to come from within. Why you think all those Buddhist Monks are happy to chill in the mountains and meditate 24/7?
If you need another person to make you feel "complete" then something is wrong. Like someone said to me the other week, the day you stop stressing over whether you're gonna meet someone and focus on making your own personal life more enhanced and work on YOU, then that's when the positivity startes to flow in. That's classic laws of attraction.
I don't wanna be single my whole life either but what scares me more is not feeling happy and content from within.
