Yes I've too been through something similar, attracting certain signs over and over.
I am a Capricorn and for a while would have a lot of Gemini friends come into my life.
While fun, bright, and witty, these young ladies were younger than I and usually caused me a lot of trouble, and I do mean trouble. My best Gemini friend- the one I felt closest to at the time, was constantly dragging me to meet guys online.
These experiences were either very close calls a couple times, or pretty annoying for myself, as I had zero interest in any of these guys, and had zero interest meeting guys online. I find it the very very last thing I would do. If I had no other option, I'd rather not date. The only reason I went with her was in fact to protect her, being the rational one.
What I've learned from Gemini's is essentially, a great and valuable couple of lessons. 1. I should be able to let loose now and then and have fun, and not worry so much. 2. I will not meet men online, I find it an incredibly numb thing to do. And 3. I need to constantly consider whom I keep as friends, while friendships can be fun, I do not need to associate with people on a whole different mental and emotional level from me, meaning immature friends aren't fun for the most part. And now that I am 35 I find many 35 year olds aren't much differently emotionally from these 15 to 16 year old friends I used to have. These days and what I have taken away from my pattern of Geminis, is to choose my friends wisely, and not to tolerate disrespect.
The most recent pattern for me was Sagittarian friends. Male and female. I got along with most of the males just fine, the females less so. One stabbed me in the back over a crush I had, while she was dating and with my brother. The other two I really do like, but do not see often since moving. Although I like them they are a little gossipy, but I love them still, it is a small fault in comparison to listen to the girls gab a bit- quite a bit, to utter betrayal.
What I have taken away from the experience with the Sagittarius pattern is- be careful who you trust and put your faith in, and true friendship or kinship from the other two ladies. They make me laugh, and smile, and help me to feel optimistic, when generally being Capricorn, I am not.
I am inclined to feel such sign patterns occur for us as lessons of life, revealed within the signs we keep attracting to us. Usually I find when we are attracting a lot of a certain sun sign, there is something we can learn from this sign in particular.
Balance.
