QOC and Irish Donna have seemed to be pretty accurate for me regarding the POI, and both saw that his relationship won't last. I don't know which way things will go there, but I do know that he brought confusion, pain, and heartache into my life. He really wasn't all that good to me. He sent me texts meant for other women, he always had something going on.
When he was married, he cheated on his wife at least 4 times that I know of and he was the smoothest liar I've ever seen.
If POI's gf stays with him, not entirely sure she'll be happy. He may try to be loyal for awhile, but past experience (and according to QOC, Stephanie's Guided Tarot, and Arriana) he won't be. QOC said there were so many women around him and in the end, he's not a one-woman man. I think she's right...
