I am reading up on your story now, SoTorn. My kids are younger and the OM is only 40 minutes away and 5 years older than her. A lot of parallels. My story is just starting. Your's appears to begun months and months ago. Good Luck. I am detaching slowly. It is hard but wish I would have done it sooner. I have done what a lof of newcomers have done. The crying, pleading, begging, etc.
She has never mentioned a divorce. Just wanted "space" and to get her master's and work on our marriage. But of course, everything wrong with the marriage was me. She can't ever remember being happy, etc. Got married for the wrong reasons.
She is in love with the guy. It is her soulmate. She then says that there are things that annoy her of him. Things that she does not like about him. SHe knows she wouldn't be happy with him either. She may be just happier alone. SHe said if she had the finances she would already have moved out and then worked on our relationship. All BS.
I am kind of hoping she just leaves and I can tell her I will send her a check of her income (not a lot) each pay period until she can get her pay switched over to her own bank account. Then I can turn off her authorized user credit cards and then not be financially worried about her racking up her bills. I have locked her credit card on my account a few times just to prevent her from charging it.
I am slowly but surely doing the detaching. It is a day to day thing. Difficult.
