So my and my ex boyfriend right now. We dated for 8 almost 9 months. We haven't been together for about almost 4 months. The reasons we broke up is family problems. Like they have nothing to do with me and him. We plan on getting back together and we both have been loyal still. We Resonantly started saying how we could both see each other getting married within the next three years cause I'm not 18 yet. And we just kinda have been talking about it a ton. He gave me a necklace in December and I gave him a ring a couple days after spilling up. It's kinda our promise to each other that we will stay together. But we haven't really said they are promises really. I'm not sure if I'm explaining Very well. But his birthday is coming up.. I wanna get him something like serious. But I don't know what to give.  Cause I've given him a ring. And just like random stuff here and there. But like I want this to be special and serious so he kinda gets the real idea of how serious I am about all this. Does anyone have any idea of what to give or what to do.
