The reason for this is that when Elly looks at her children, she's convinced that their reality of being born helpless and ignorant is unrealistic not just because she has to give up her precious free time raising them but because having them be the tiny adult joke machines would give her someone to talk to about things she's currently experiencing. Having to listen to Mike, Lizzie and April bore her with useless things like what's happening in their useless little child lives makes her feel bad because other people expect her to do something strange and care about something that she isn't experiencing. If only the kids could be made to realize that since Mommy no longer has to deal with it, it's no longer important.
That being said, it's not just her connection with her kids that got screwed over by the flickering blue parent. Most of the reason she's been a crappy friend to Connie is that she looks at a messed-up, angry and confused woman who doesn't know what she wants out of life and sees a horror freak from a day time drama having it all. Eventually, Connie had to leave town to get away from the damage her idiot gal pal did. It's like how she treated Annie like a leper because television told her that the only reason she didn't toss Steve out was because she caved. The other archetype of the matron having a club to beat a weak husband over the head with intimidated the Hell out of Elly and made her feel like a weakling and thus had to be ignored.
Finally, we have to remind ourselves that she still thinks that the reality of Farley's not being a dumb guy in a dog suit is unrealistic and unfair is that if she admits to being a loud, angry woman doing something futile and confusing, she'd have to cop to being stupid and bad and that would be bad.
