Keep putting yourself out there. You're not gonna meet your future some by sitting at home alone (unless it's the food delivery person I guess). Even if you only have one friend (or none) who is available that day & can join you, still try to go to concerts, bars, bookstores, restaurants etc alone.

Also just because things don't happen romantically with someone doesn't mean cut them off. Sometimes people are meant to just be a fun friend/acquaintance and you can expand your social circle through them, and meet a romantic partner from that.
