I totally agree with Ivan...this is your goal long term. Everyone ultimately has to do it & maintain it, if they haven't already.
If you want a shorter term/quick fix, being more fun/interesting and leading should help out a lot here. Instead of:
AFC: Hey whatsup?
HB: Nothing, you?
AFC: Nothing....
It should be something more like:
AFC---> PUA: Hey Whatsup?
HB: Nothing, you?
PUA: got off work/school earlier, finished up a workout at gym...planning on heading over to that new juicebar they just opening on ABC street next to your house (or city, whatever) in a bit....you should join
HB: Can't...I have blah blah blah blah
PUA: Oh come on, it'll be fun. Plus I can show you that (monument/interesting item/whatever/tell you more about what we were talking about when we met etc.)...
HB: hmmmm... (unsure & thinking about it)
PUA: Tell you what. I'll come by in about 15 min. to pick you up. I can't stay out too late because I have (work/school/whatever) to do later/in the morning/afternoon/nite/whenever. (false time constraint per Mystery, or REAL if you do manage a busy life-which you should). Be ready when I come by. It'll be fun. See you in 15.
HB: (Finally caves seeing how awesome you are) Ok. Cool see you then.

Always lead my friend and have a busy/interesting enough life where your game is congruent.
