From a personal point of view I agree. It is frustrating to see that. In the real world you are not going to leave your husband or wife and only see the kids every Wednesday plus every second weekend because your spouse looked at your phone. It's non-advice to offer that in most cases. Now, if you were two months dating on the other hand and he's checking your phone, my advice would be to run like Gump.
With an open forum, you'll get anyone posting, even people who give poor advice. As much as we'd like to though, we can't ban them. Posters can however point out the obvious flaws in their 'advice', provided it's done in a civil manner and keeping the OP in the loop rather than two posters going off topic and having a nitpicking debate on it.
