This is of course completely illogical.
Take it from someone whose parents fought like cats and dogs...an unhappy couple staying together does no favours at all for the children. Better two stable households than one unstable one.Not illogical at all. It may not be a healthy relationship and maybe the couple does have an unstable marriage, but Eve getting involved will only make things worse, for everyone. It's completely logical, she needs to get out.
Eve should get out and away from both parties, get some air and clear your head. No need to get involved with a married man, no matter what the status of their marriage is, who has cheated on who and if kids are involved or not.
Peace Out~
