Odd, I have plenty of social interaction and haven't had facebook in over a decade. I even moved states and made an entirely new friend group, all without having a facebook.
Your problem is you lied to someone you were trying to create a relationship with. What did you expect? That she wouldn't see through a hasty attempt to make it look like you actually used the account instead of just being a dead account? For all she knows, you're going to leave her in a ditch somewhere and you're just hiding your tracks...
Just be honest, and if someone's not going to want to hang because you don't have a particular social network already, they're doing you a favor by not wasting your time.Find better friends that you'll actually enjoy spending time with and communicating. Get a hobby or something...
And here I thought I couldn't afford my house because of all that avocado toast...
