One more piece of data
The one thing I think is important that I didnt mention is that as this started, we all had a 'deal' that if anyone started to fall in love, we would talk about it immediately. This didn't happen. They kept their love a secret from me and, worse, she started pulling away from me. This resulted in her being cold, distant, and unapproachable. As a result of some of my actions (speaking to a female friend about this), we got into a big fight and thats when the truth came out.
So I do have a trust issue because of the fact that they lied to me.
