1. I think it's plausible that JA called Gus that night, it's typical drama queen behavior. Everyone she knows is sick of her s**t, so she leeches on to new people who didn't figure out her angle yet.
2. I think the judge on Dr Drew last night missed the mark when she insisted that JA must have been in love with Travis. Since he wasn't rich or important, the only conclusion is that JA was really in love with him.
I think she's either underestimating or doesn't understand that all this is relative. To someone in JA's position and economic status in life, Travis represented a degree of affluence, the kind of person who "doesn't have to worry about paying the bills," in JA's own words. That was something she didn't have and coveted. Maybe she "loved" him (although I doubt that word can be used about JA), but more than that, she dearly wanted the good life he represented.
