Waiting for forever...

It has been seven months since I visited Anna in Russia and almost five months since we submitted our I-129F petition for alien fiance with the USCIS. When we filed the petition, they stated on their website that it was an average 5 months for approval.
Today I checked and the average has risen to 5 1/2 months. It seems that the longer we wait, the longer they prolong it. How long can this go on? If the service was free, I might understand this, but this service did not come free and I had to pay $340.00 to submit this request. Anna tells me it will take 120 years for the process to end, but I have remained optimistic but now I think she may be right so it seems.
Both Anna and I are getting extremely frustrated while we still wait for any response on our petition.
Unlike most couples who can talk on the phone at their leisure, Anna and I are limited to the moments we can speak on Skype. During weekends we can speak for nearly 2 hours as we communicate over Skype.
Weekdays are limited to an hour, now cut short to 45 minutes due to some complications that have arisen.
Every day seems to be an eternity as we wait for our brief moment we can talk to each other. The sad part of this arrangement is the fact that Anna is tired and ready for bed when I can talk to her during the week.
In fact, Anna was so tired the past 3 days, I could not even talk to her because she was so exhausted from work and the constant demands of the children. Now it seems our conversation is limited only to 4 hours during a weekend. I can't say this is the best situation, but even though we are frustrated, it will not stop us. We hope that within the next month we will have our petition approved and that will enable her to apply for the visa to come here to America and finally be with me.
Obviously she cannot immediately come here after our petition is approved but at least I can say she will be able to apply for the Visa. We will have to wait for another 2 months before she can even get her interview. If all goes well during her interview at the U.S. Consulate in Russia, she will be allowed the Visa to come here as my Fiance.
The time seems to crawl as we wait and now each day feels like a year while we wait to see each other for a brief 45 minutes.  I hope soon our suffering will be over, because I must admit, this situation is nothing short of torture for us and it feels like we are waiting for forever...
