Welcome to the forum. There are no hard and fast rules with how things work. It's a matter of figuring out how it works for you in your particular dynamic.
I'm sorry I have no advice on how to meet people. Just be open to possibilitites. Let things go where they are going to with people that you meet. Try not to have any great big expectations. Not everyone is going to click with you romantically but there is always the chance of friendship (and with friendship comes meeting friends of friends).
Everything will be ok in the end. If it's not ok it's not the end.
