@Penelope: I had my first reading with Ness like a week or so ago, I don't remember, but she super sucked. I think she has more of an opinion than any real abilities. She was way off, way wrong, way everything.
There is one reader that I know of that is THE BEST at picking up 3rd parties without you even asking and she's good for the here and now energies, I wouldn't pay attention to her contact predictions, or outcome prediction, but if you are seriously confused and worried about a third party, she's fantastic. If she does pick up a third party, she will tell you the nature of the interaction, whether it's serious, flirtatious, sexual, etc. She's the ONLY ONE who picked up a third party (that I wasn't even suspicious of there being one) way back in 2016 without me asking. I didn't believe her at first, but then I found out two months later that she was right and there was a third party during that time. She'd also told me it wouldn't amount to anything and was just flirtatious, she was right, it didn't amount to anything. No other psychic picked that up. I was so upset but then each time I'd feel there was a third party again, I'd call her and have her do a general reading and just ask "I'd like a general read on (insert name) and off she went. There were times when I thought there was a third party, but she didn't pick it up and I'd find out later that there wasn't and she was right. Other times she'd tell me when there was. Recently, I had called her November 7th when I felt strongly there was a third party, she indeed picked up a third party but told me the third party was "in and out and flirtatious" and wasn't consistent and that the third party would be gone soon. I called her two days ago and she picked up "lingering and fading" third party energy which meant the connection was in progress of being severed and will be completely gone soon, if it wasn't already. Her name is Aliza on California Psychics.
Aries has picked up third parties as well and explained the nature of said connection as well. I do think Aliza is best for that particular topic though for the here and now.
