Not everyone is a telephone person. I rarely answer anyone's phone calls, especially if I'm at work and in the middle of solving a problem (75% of the time). I phone my mum twice a year (and even then it's awkward). If me or DH is abroad for work, I call him 0 times (even if it's for a month).
My DH calls his mum every day, and has also trained me to become better - I can mostly manage a 10 minute conversation, sometimes even an hour! I also answer most of his calls (only 3 missed calls today, but was a meeting), and he promises to only call for essentials or emergencies.
We have found an alternative for communication: WeChat (the chinese version of WhatsApp). You can send as many text or voice messages as you want, when you want, even add photos. The other can listen to them and reply when they wants to.
This works especially well for me, almost like a shared blog - I write 50 msgs on how I'm hurting and where, a pic of weird pants someone is wearing on the metro, a joke heard. At some point he replies with an "awww" or "Oh that sucks" (I taught him the replies I want to see
), or vacation plans, complains about my dishes (and mostly washes them anyway), asks when I'll be home or should he buy something.
My point is, try finding a communication method that suits you both, and is flexible enough.
