suggestions?

My best friend had unprotected sex this weekend and so when she told us at school my other friend and I immediately took her to planned parenthood to get plan b. My question is: is is completely unreasonable of me to be pissed at her boyfriend? I mean, she made a mistake having unprotected sex, but this isn't his first time around and I feel like he should have been more considerate to her (I.e. Bring a condom, stop pressuring her into sex when they don't have a condom, realize that after she could get pregnant and support her a little)? I feel like so many guys have no consideration for girls when it comes to getting sexual pleasure and have really just lost hope for men in general. I kinda want to confront him to teach him a lesson but I don't know if that's the best way to deal with the situation. What would you suggest I do?
