You never know what goes on privately, behind closed doors. When a woman is perceived to be perfect or to have more money or higher status than other women, it is a very lonely place for her to be because many women just don't like feeling inadequate because of someone else's talents, looks or possessions.
I've been career successful in my life and have a happy marriage, comfortable lifestyle and a wonderful husband and kids. I've had to work very very hard for all of that, but I find that I have no close female friends to call on because I've found that many women can't handle what is only their perception of my perfect life. It makes them feel inadequate and they reject me. I can't help what I have, but I have it because I'm hardworking, I love others, I support my family and I like people. Those who reject me for the 'surface' perception they have of me don't see that I've had heartache, grief, poverty, weight gain, weight loss, malnourishment, difficult childbirths and the psychological effects of that, all of these hurdles in my life that have shaped me (literally and metaphorically) and made me appreciate what I have now.
Everyone thinks that loneliness only occurs in old age and solitude. Let me tell you that loneliness can be affecting someone in a crowded room; the belle of the ball, Miss popularity, the class clown, the workaholic, the busiest people, the richest, the most successful.
If something is sticking in your throat clear it by either swallowing it or spitting it out, recognise that you are responsible for controlling your feelings and get on with being a true friend to this girl as you just don't know, your friendship could be viewed by her as one of the most priceless possessions she has.
