I'm sorry you were unfriended by your cousin. Snubbing can be taken to a whole new level on Facebook!
I think the crux of the matter might be that the word 'Pagan' has different connotations for you than it does for your Born Again relatives. Had you written, 'I feel close to Nature and revere it' - a central tenet of Paganism - you might have had a friendlier response.
Paganism has been the traditional enemy of Christianity down through the ages, dating back to the earliest period of expansion of Christianity, when its growth was dependent on converting Pagans. Christianity and Paganism were competing mind memes and so it's not surprising that the Christian spin doctors of the day were spinning madly against the alternative.
Even in today's society, particularly in some Christian circles, there is a residue of the feeling that Paganism is primitive (in a bad way) and that those who engage in it are of sinister intent.
Here are some of the things your Born Again family might believe about Pagans:
They worship the Devil
They use black magic for evil purposes
They harm human beings and animals
I'm guessing that this does not describe you and your experience of Paganism at all. You probably see yourself as venerating the natural world. You pay attention to and celebrate the passing seasons. Perhaps you are also interested in using plants for healing purposes and, all in all, you are a good, loving person.
In short, you have not yet been able to communicate all that you are to your cousin and other relatives through using the simple word 'Pagan'.
Your sister, a Buddhist, has been accepted. So there is hope that if your relatives were to have a better understanding of what Paganism means to you, you might also be accepted into the fold.
Why not reach out in love to your cousin? Without wanting to sound too cheesy, love is what's important here.
Why not find a card with a beautiful picture on the front that expresses perfectly the special feeling you have about Nature? You could write a few words to your cousin, letting her know a little about your beliefs. Let her know that you respect her beliefs too and have no interest in changing them. Maybe you could recall a cherished memory of time you spent together in the past? Tell her how much it would mean to you to have contact with your father's side of the family. Of course, there may be aspects of your belief system that your family would find difficult - and a bit scary - I'm thinking crystals and cauldrons! There's nothing wrong with maintaining a diplomatic silence on those aspects. Concentrate on finding common ground.
Having said all that, a word of caution needs to be expressed. Your cousin's views might be so deeply entrenched that reaching out to her wouldn't work and you would have to be prepared emotionally for that possibility.
In the end, perhaps it's your Dad you are missing. (I miss mine too.) Remember that some of his essence will be in you, your children and your siblings. And, as you move through life, you will also find, quite unexpectedly, some of the qualities you treasured in him in others, completely unrelated to you by blood.
