Need help about a friend

Tell me honest truth here my friend in Perth is her baby is due In Oct a week before me and she's been through her bank accounts n realises, now that around the 27/03 while her husband slept separately from her cos her hormones were pissing him off and they'd been arguing, she's realised she locked her room door, put a Zoosk account (she used an email at work for the ITunes receipt confirmation and she’s done it from her individual account so he won’t see what she bought) and she signed up for an RSVP account (they’re like tinder and hook up sites here in Aus) and stated that she's a "widow with a one month bub” and has even contacted an ex (well not really an ex a guy who she thought she'd dated but used her just for sex in her teens) on facebook and arranged to go to the beach in the week of the 27/03 or has tried to sneak in a “quickie or plan one with him on her return out of her shift at 8) she says she wanted to have sex outside her marriage since her husband was in a room other than hers and has complained about him to the guy who thinks they should catch up and that he’s changed and he’ll look after her baby ( mind you I knew the guy she never listened he just wants that ass and that’s it hit it n quit it he had a good time with her then dropped her to go to Uni) but to pretend her husband caught her she sent a text from her phone pretending the husband didn't want the ex "contacting her for sex as she's over him." what should I tell her that she's cheated or emotionally cheated or she should divorce Cos the guys a looker he’s faithful and treats his kids right and doesn’t, deserve this n she is preg with baby 6. Personally I think she deserves to be in hell. Is it cheating if you only contact them n flirt n get numbers n text n not physically do things she asks me and is it ok if she stopped now n realised or is it that they’d been in separate rooms n she’s allowed?...
