What in the fuck

So here's something that makes me crazy..the WORST people to get pregnant..ALWAYS do. As you will recall, I used to work at a preschool, with mostly lower class (as in pretty poor) families. Which was no big deal, the kids were fantastic. But, we had AT LEAST one alcoholic drug addicted mom, and more then 10 kids who one or both parents were in jail. So, not the best parents. So can you please tell me why the said mom (alcohol/meth) is pregnant but her felon boyfriend and then today I find out that another mom is pregnant by the man who tried to beat her to death last Christmas, that she put in jail and then proceeded to bail out and her ex-husband was in jail for manslaughter. Seriously!? Why can't it be me? My husband and I would be great parents and we are stable, we have income, we aren't hooked on drugs or alcohol or addicted to anything else and ugh. I know. I am completely bitching, we've been trying for like 3 cycles, not very many and I just get pissy. Ugh, Im done bitching for the moment. Well until the negative pee stick that I am sure is inevitable.
