21 M been in a rut recently I've been single for over a year now, it started out as me not caring to much.  This slowly turned to depression, without me realizing it.  I stopped exercising, gained 30 pounds and felt like shit.  I have a good friend now and he helped me out of this, we workout everyday and run.  Gained some self confidence back, lost 7 of those damn pounds.  

Recently I had my first good interaction with a girl, she was a friend of a friend.  I had a great time, and even my buddy said he could see the connection there.  Ended the night with kissing and got her number.  Next night we texted and everything seemed great, lots of lol's and smiley faces from her end.  Next few days I was busy, so I didn't message her at all.  Now 5 days later, I sent her a message and never got a reply.  

What I would like to know is if waiting 5 days was too much time to ask to see her again and I fucked this up, or just ignore this and try again tomorrow?
