I plan to just block the communication methods tonight when I get home. If she asks why, I would like to go with the indirect "I feel like it is happening...." approach. Do not want to let her know I am monitoring, though that was not difficult. She left it signed on.
If it gets to the point, I will request to monitor, if she does not have a problem with me doing so. Biggest problem is, she sees this guy everyday at AA meetings. She is also home everyday being without a job, claims she is at least, doing homework (in grad school). Perhaps I can request she puts in the ending for him to go to different meetings, or that she does. Regardless, if her mom finds out, or really her entire family, she will likely be disowned unfortunately. Same with leaving the house. Consequences, she knows them. Mr. delusional manipulator seems to think otherwise, or that it would just be better with him regardless. A lot of her grievances are just kind of strange to me....and everyone else. Like they were put there.
W told her mother herself what she did (I did not) and claimed she cut it off. She may have for a week I would say...maybe. I could not confirm until after 2 weeks though. Second time around will likely be much worse, if it gets to that point.
