Ok here's what do you.
First, you're going to need to get in the habit of charging your phone to FULL EVERY night. You want to be prepared when she calls. Talking drains the battery quickly. Don't be that guy that disconnects 3 hours into to the call because his cell was only at 40% :nono:
Second, get an external backup charger for your phone. Better yet get two. You never know when you're gonna have a 12+ hour phone call with your GF. I recommend two so you can charge one while you use the other to keep talking. I've done several multi-day calls using this strat. Total life saver! Still no sex yet, but I feel it coming. Imagine where I'd be if I DIDN'T talk to her every day for 7 hours?? She probably wouldn't even hold my hand hehuhuhehueh
Third, take very good notes while on the phone. Treat it as though you're studying for a class and there could be a pop quiz any moment. My "cheat sheet" as I call it has saved my ass so many times. She's been disgusted... err, amazed at my ability to recall in exact detail what she's said. I sometimes correct her because even she forgot what she said hours ago.
Fourth... bluetooth or blueballs, as I say. You gotta be bluetooth compatible man! Whether it's walking around or driving in car, you need to be able to talk to your GF seemlessly. All it takes is one, "Sorry love can I put you on hold for a second the firefighters are trying to get the door open" and THAT my friend could ruin your chances of her touching you one day.
Fifth, download some scheduling software so you can more efficiently arrange her day and schedule things for her. When she calls asking what is lined up you need to be on top of it. Her doctor's appointment got bumped up a day? Update her schedule and notify her pronto. Do NOT call her though, it can be inconvenient for her to answer the phone. I always send a text message notification about updates to her schedule.
Sixth, do NOT talk over her. Number one way for her to call even less. If you have something to say, be as succinct as possible and only say it if there's a pause in her monologue.
Seventh, never under any circumstance end the call without thanking her and telling her how much you appreciate her time. For example, today as soon as she stopped talking I could sense the call was over, so I quickly said "Well, thank you so much for calling I love you more than anything and if you look outside your door you'll see a special delivery of" before she hung up. See what I did there? I ordered chocolates and flowers to her door AHEAD of time, just to tell her at the end of the phone call to surprise her. I bet she'll call back again later today now. Winning.
Eighth, quit your job. Avoid going outside in general. You need to be more available to talk to her on the phone. When she's not calling try to use that time to sleep and "recharge"
But don't get too comfortable, because she may call at any moment. Keep the phone by the bed or better yet strapped to your body. I recommend an arm strap. I rarely let it ring more than once. It takes practice.
Nineth, don't be afraid to take out a loan if you need more cash to pay your phone bill or fund misc costs like software to manage her schedule, surprise chocolates, or her phone bill. Have a garage sale and get rid of anything that doesn't directly support your calls with her. Since you no longer need to go anywhere, selling the car is a good way to get some extra cash.
Tenth, look around the corner of the street you sleep on for any spare items you can sell. Do you really need that box to sleep in? Let's be honest concrete is really not much more uncomfortable than cardboard. That shopping cart can probably be pawned off for a few dollars too.
Eleventh, never give up. By this point you're homeless living on the corner of the street with nothing but a phone and some backup chargers you occasionally charge at the Kinko's down the street whenever the manager isn't around. You can make a surprising amount of money by selling blood. Think outside your box... which you sold.
Twelfth, don't hold out on her. Just because you're dying of starvation doesn't mean you can't utilize your last remaining energy to listen to her talk. It takes almost no energy to listen, don't be selfish.
Thirteenth, some time before you die passed out on the side of the freeway all alone make sure you set up an appropriate voicemail message. When she calls she'll need to know you're dead and who to call next. I recommend something like, "Hi sorry I can't answer the phone right now because I'm dead, but you can call my bro Jake he's at 995-3471. Also, if you look outside your door you'll see a lovely delivery of..."
