I think Wicca is a very uplifting religion. While I am another flavor of Pagan, learning about Wicca is how I got more settled into my spiritual beliefs so I am aware of what Wicca is for the most part. What ticks me off is when people say "I'm Wiccan, blessed be! (blah blah blah.)" and not even know what Wicca really is. Mostly it's the teenagers since I have to be around them as I am a teenager myself but I've also met 40-some year olds who are"fluffy bunnies!"
You know, if your boyfriend thinks you Satanic, ask him if you are LeVayen or Spiritual? If he thinks you something else than what you are, he obviously doesn't know you well enough, in my opinion at least. Stick to your faith! At least you have it. The world needs more people with faith no matter what flavor as long as it is helpful.
