People here are making it sound like the pill is barely effective. If you look at the stats, most show that it is effective approximately 99.6% of the time, which, allowing for statistical margin of error is more or less 100% "when taken correctly." Condoms are far less effective, and if you knew anything about statistics, the added effect of condoms and birth control pills as combined methods of contraception is negligable.
If you're only point is so that sybolically, both parties "share responsibility" such an assertion is rubbage. That makes as much sense as an eye for an eye.
Certainly, until someone is in a trusting relationship with someone who is tested clean, both parties should do what is necessary to protect eachother and themselves. That said, when someone is in a trusting relationship, then I do believe that the woman taking the pill alone, makes the most sense, and is not necessary to do both, and there is an infinitely better experience without a condom. If the woman is not taking the pill then it is a mutual choice, but if the woman takes the pill, and only asks the guy to use a condom because she is irresponsible with using the pill, then I think it is her fault. Condoms break so to only rely upon condoms is stupid.
If she throws up the pill, she can take a double dose and it will be fine or they should ward off sex until after she is safe again, and they can use condoms in the interim to be safe. But you know when that happens, and there is no need except when it happens.
I'm all for sharing responsibility where it makes sense, but not just for the sake of sharing.
I think the bigger issues are: his laziness in bed (not having to do with condom use), his refusal to take an std test, her trying to put off her irresponsible pill taking on him, and her using the bs scapegoat of the "mess" to bolster her argument.
