Also, everyone on Mumsnet is absolutely fine, in fact happy, about their husband/ boyfriend having loads of individual one-on-one meet up's with female friends for lunch// dinner/ cinema etc.
In real life, most people would be extremely pissed off their husband/ boyfriend was "new best friends" with the attractive girl in the office, texting all the time and arranging regular one on one meet up's . They just would be. On Mumsnet you'd be considered controlling for this.
