Playing With Fire

So #1 has been calling me A LOT. I love our conversations and he makes me laugh, I look forward to his calls and miss him when I don't hear from him. I was weary about meeting up with him or anything because of #2 but last weekend something happened that totally diverted my thinking. I went out with a good friend of mine and we ran into #2, well he was with someone. So seeing him with someone else and seeing that it didn't bother him to be with someone else around me made me snap and realize that he's content with how things are between us and isn't going to change anything. So why should I worry about who I'm with whether I'm around him or not, and if he finds out somehow, who cares!? I think it was what I needed so that I can let him go and move on or whatever this is going to be. I saw #2 the other day at his work and he talked to me and all, I just wished we would have been somewhere different or somewhere alone. It's weird, I spent so much time trying to get over him, and I was just about there and then boom! he starts paying all this attention to me. I feel like he was meant to be a part of me some way somehow. I feel the same about #2 but more on a friendship level. My question now is if something does happen between me and #1, how is #2 going to react, and if #1 ever finds out about #2, how is he going to react? I'm playing with fire big time, but maybe just maybe I won't get burned this time.
