A marriage analogy eh?
What if you had a wife, that was beautiful sometimes, and other times not and she's really starting to show her age? She was cranky some days, some days she didn't work at all. She kept giving you stuff but it wasn't the stuff you wanted. She didn't keep all of her promises and those she kept, she would just deliver on them whenever she felt like it. 13 months ago she said she'd redecorate the living room and still hasn't gotten around to it. Her voice is whiny and screechy and not at all pleasant and she kept promising to work on it but never got around to it in 15 years.
Meanwhile you see other wives that are still beautiful, have a voice like an angel, work hard and give their husbands the stuff they really want on a regular basis. Best of all, they don't cost any more to date and marry than your current wife.
Now what?
