"Oh," Lavender replied, and then she frowned slightly. "Well that part I can help you with." She took a moment to consider her words and then said, "Different people love in different ways. There are some people who can only love one person ever, and there are some people that can love more than one person at the same time. I used to think that I was the sort who could love multiple people, until I really fell for Seamus. And now I know that I will always love him, forever, and that I'll never love anyone the way I love him. But Shay is like those people who can love more than one person. He loved Dean and I both at the same time, in different ways. Because I love him, and I want him to be happy, he knows that if he really wants to, he's free to be with other people... although I've requested that he never tell me about them, because I personally don't want to know. But at the same time, what I do know... is that no matter if he feels the need to be with someone else however briefly, he will always come back to me, and he will always love me. Because we're a family."
She stopped and took a deep breath. "I got sidetracked, just a bit. What I'm saying is... it's okay for you to love two people, Colin. It's even okay for you to want to be with both of them. But where the issue comes in here, is that both of them have to be okay with you being with another person. Because it can't work, if they're not. In a relationship like that, the people involved have to be aware of it, and okay with it. If they're both not, or one of them isn't... then I suppose you do have to choose, sadly." Seamus had. He'd chosen her, but she didn't mention that right now.
Lavender paused to pour the tea into the cups, setting one down in front of Colin before taking a seat next to him at the table. She cupped her hands around her warm mug and just listened to him talk. One of them has to get married and all. And then suddenly, with those words, it clicked. Zach. Zach had just been talking about how he'd told his boyfriend he'd have to get married and how worried he was. It was the two of them! Zach and Colin! And all this time she'd never known!
Of course she didn't say anything out loud, just let her eyes widen faintly for a brief moment before she pushed that aside. "Yes, love. I think that basically, if you know what they want, then you have to figure out what you want, and how they could fit in to that. You have to figure out what would make you the happiest, in what situation you would be the most content."
