Thank you for all your wise words. I will definitely be considering all that you have brought up. I'm also going to encourage the two of them to get to know each other a little bit more and see how that goes for now.
As for poly groups, I don't know if that's something I would be comfortable with, and I know for sure that my hubby wouldn't. I don't know where I stand on the notion, really. I am what I am, which is to say that I'm in love with two men, and that's all. But I don't think that a polyamorous lifestyle is necessarily for me on the grander scale of things. Know what I'm sayin'? Yet, I've been thinking a lot about these things lately, so who knows. I'll keep that piece of advice in the back of my mind at least.
