Yes, I think that probably earlier. But I'm not sure. I think they went there a fair bit in the early days of their relationship.
As to whether they were allocated separate or shared sleeping arrangements, I have no idea. In the HLN interview I mentioned, Chris says "she was down there in a different bedroom". I think you could take that either way, that is, she was in a different bedroom from where they were having the discussion, or she was downstairs in her own bedroom.
I don't think it matters hugely in the end though.
I'm going to go out on a limb here and hope this straightens things out.
The Hughes are LDS. I understand they were and are members in good standing and follow the tenants of the Church. That being said, they would NOT allow 2 members of the Church, who were NOT married, of the opposite sex, to share the same bedroom. Their house, their rules.
As far as being "rude", is it not common, when you visit friends who live quite a ways from you, to stay up late and catch up? JA was NOT a part of TA and the Hughes' relationship at that point, if she ever was, and why wouldn't she say she was going to sleep because her "attention span" is very limited if it's NOT about her? She probably heard her name being mentioned through the vents and snuck up to the door.
JA has made EVERYTHING look nefarious, perverted, and disgusting........will any of you ever look at a Tootsie Pop, a childhood favorite, with out going "Ewwww!"? She is being given WAY too much credit for the lies she spews out of her mouth.
Unless proof is brought to light to show otherwise, I will believe any LDS member involved in this horrible situation. I do not believe in their faith, but their honesty is far more reliable than that of JA.
