Guys, he's taking long to reply.. how do I deal with it?

Please do yourself a big favor and relax..... no need to be anxious, he is going nowhere if he is meant to be with you as a friend or whatever the case may be. Just don't think so much about things like this, they are mind bothering..... talk to him and tell him how you feel, maybe that will help him speak up too.. all the best and let me know if you need further help.
