My experience has shown me that in most cases, the truth will set you free. (The preceding does not apply to rich people, who usually buy their truth *O.J.*).
If Skul has a real desire to vindicate himself here (which is certainly low on the "to-do" list, imo), he could always get previous girlfriends to post here. He's an old enough guy to have had other girls beside Groover.... How did he treat them?
If Groover has a real desire to validate her claims, she should be filing reports with police (and not with TW). However, in the interest of TW readership, let's see some credit card reports when she was in hospital of huge transactions.
Either way, even on this small world audience via a gaming forum, if Groover is right, Skul needs help. If Skul is right, Groover needs help. Either way, these are some pretty serious allegations, and both sides could sue, if they desired.
Personal opinion: My gut says that I'll believe Skul first, having met the guy. I'll go with innocent before proven guilty.
