Sounds like your W is losing a grip on her OM and trying to keep you on the hook for money etc cause apparently the stud muffin isn't forking over the cash she needs or anything else her little fantasy affair thought he'd be providing.
You don't have to give her a dime. She decided she wanted out...wanted OM, well, she's got both now let her stew in it...she's being dumped apparently and now she's beginning to see what that feels like.
Is she remorseful? Has she cried about how pathetic she feels for what she's done to you, your D and your M?
Or is she just whining about herself and her own unhappiness?
If she starts patting you on the butt, be careful, cause she's only feeling for your wallet.
Tell her to get herself together, get rid of the OM, seek counseling and then, you'll be happy to start dating her again and working toward reconciliation.
If she doesn't have much money tell her to get a better job or a second job and that you'll pick up the slack in the child care of your D while she works.
Reality is a bitch and your wife's having it shoved in her face...I have a feeling lover boy ain't lookin like such a knight in shining armor to her right now.
