When someone close is drifting away you can always feel it on the emotional level. Less phone calls is not always a sign of the person drifting away, maybe they are just getting busier with their job or relatives. At times we want the person we care for to be paying attention to us 24/7, and that way we are just killing a relationship. Every human being needs some time to themselves, as everyone has their job, relatives, interests and hobbies. If a person is really drifting away it normally shows in the way of them getting more withdrawn, less interested in spending time talking and discussing with you even if they have free time.. But if they don't have that free time available you shouldn't get any negative feeling! And the best way to see if you are still important and mean a lot to your close person or not, is when you get some problems. Will they be there for you? will they try to really help? Answers to these questions are also answers to whether they are still close to you or drifting away..
