Engagement

My bf and I have been tg for five years. We r moving in together in two weeks. Everyone’s been asking me when it’s going to happen, I wanna say first half of next year? We’ve talked about it, but he does get really shy when I bring it up sometimes which concerns me. My brother is much younger and isn’t even in a long relationship and already has funds set aside for a ring. I don’t wanna be pushy or pressure him at all but I’m just wondering if he’s even planning on doing something like that? I know he doesn’t have funds saved separately for that. Idk how to even bring it up cuz it’s awkward and he definitely Shys away and I hate being pushy.
