Expand my friendship circle

Okay so I have broadened my circle- new friends that I have met through uni are:
Olivia: My age- we graduated the same year of highschool. She seems lovely. She has spent severaly years working overseas- so she is quite grounded.
Freya: She’s fresh out of highschool. She is a triplet from Tasmania- she has a sweet natured personality.

It’s thinning out- as friends pair of and begin their journey never to be seen again in the world of coupledom. Leaving us singles to create a new social life…. I need wider friendship circles.
