Please help!

ugh im so sorry you're going through this

i would just be honest with your DH and let him know that even though u know there is nothing going on, u think there might be something wrong with this woman that she has chosen to latch on to him. it's one thing to be friends, it's another thing to talk multiple times in one day. if she needs to talk to someone about her personal issues, tell her to get a shrink. i wouldnt want my husband being the resounding board for another woman. i have a similar situation with one of DH's old friends but she only calls him like 4 times a year - if it were more than that, i'd probably say something to her

good luck
