You don't need a significant other to be complete.
You guys probably have heard the sayings before.
"He/She is my other half."
"He/She completes me."
I reject those notions, and you should too.
Because you, as yourself, by yourself, ARE COMPLETE.
Finding a partner that brings you joy should be like discovering the combination of French fries and McFlurries. Before that landmark, you were perfectly fine with having just one or the other, and you thought they were magnificent by themselves. The combination didn't make one or the other better; rather it created an entirely new wonderful entity. But if the cashier says, "Sorry our McFlurry machine is down", you aren't gonna be like 'My fries just aren't complete without a McFlurry'. You may be like 'Darn' for a moment or two, but you're probably still going to get those fries, and still going to enjoy them like you did before you found that heart attack-enducing combination.
My point is, YOU are the main course. You are the ice cream sundae AND the cherry on top. You, as yourself, by yourself, are complete, and don't ever forget that.
