Fellow DBers...please help me help a potential walkaway friend... Anyone who's been involved in an EA around? Sandi?

My friend told me tonight that she's been talking to a guy at work a LOT and the other night they kissed. She says she doesn't understand why she's obsessed with him or how to stop texting.

She's been with her BF 3 years and they live together, and the OM has a GF who he was supposed to move in with - but he's cancelled the move because of my friend. I think he is going to try to pursue her (which worries me). My friend feels awful and guilty and she's told OM she wants to cut contact but she is struggling. I told her I've heard it's like a drug and she said "oh my god, YES! how do you understand me?" (Thanks, DB!)

My friend is a great person and I can honestly say she is one of the the last people I ever thought would have an EA or PA, so I really understand better now how easy it must be to get sucked in.

She and her BF are such a great couple, and I can't picture them not together. I want to help her/them if I can.

Anyone with experience of an EA, any advice on how to quit the addiction? All I could tell her was expect withdrawal. I imagine seeing him at work daily won't help...

I also asked her what's missing from her R and suggested doing some 180s.

Should I tell her it's an EA? I didn't tonight because the timing wasn't right and I wasn't sure if it would help her or not.
