She's back.... but still with him

[HopeFilled]

Well, I'm a long time reader, first time poster... Last week my W moved back home and while things were rocky, it seemed things were getting better. That is until she came home one day with hickies. She tried to hide them with make up... and lied that they were from before she came home, but in the end confessed that she was seeing him again.

Now I'm trying to figure out-- do I give her yet another chance, since she really seems like she's trying to get over him, and let her move back in... or stand up for myself (something all my friends are telling me to do), asking her to pack up until she's ready to give him up. I feel like her she's almost over the OP... but now I'm worried that she may not get the message that this isn't a game.
