Truth

So I’ve been dating this guy and we’re talking about getting a place together and so far we’ve been completely honest to each other but there’s one thing that I haven’t been honest with him about and it’s the fact that I live with my friends uncle I told him that I live with my uncle but I’m scared that if I tell him now that he’ll break up with me for not being honest should I tell him or just keep it to myself I hate not telling him from the beginning but I thought I’d never hear from him again when we met we weren’t exactly ready for anything serious and now I just thought that once I’d get back in the dating game that I’d have my own place by then but now I’m just scared to tell him what should I do. Please only advice nothing mean.
