While I have always been a proponent of being friends with someone before you date them (it worked for me!), it might be risky if you date your best friend though.
You've talked to someone over a dating app for a few weeks, and you both finally decide to meet-up in person... but now it seems like your date is running late.
If you've been talking to someone for the last couple of weeks online, and you both decide to meet up for a date in person, what is the worst thing that could happen for you?
