It is not that simple to equate a (perceived) need to escape from women to a mental illness. Female groups do behave differently than male groups in that they assert dominance and rank by psychological means whereas in male groups this happens more via physical means. It can be very hard for both women and men to enter a 'different-gender group', let alone to get accepted and feel comfortable. Especially in fields dominated by one gender, like, for example, construction, programming, education and child care, or health care this lead to problems and strengthens the trend of one-gender dominance.

In the last decade or two primary education has become a primarily female field even to that extend that male teachers (and teacher students) have chosen to leave the profession because they didn't feel at home in that environment any more. If you talk to them you'll hear stories about, basically, psychological war-fare among their female colleagues that they didn't want to get involved in but were forced into nonetheless. In these instances feeling the need to escape from women is quite natural.
