I made it through living with roomates in college for two years. I moved back home for the last two.. just because of money. BUT I can successfully say that I made it V* free! And my roomates never got sick unless they drank too much, but that doesn't bother me as much because I know I won't get sick from them. Honestly, just keeping things clean and avoiding germs is the best you can do, and it really does pay off.

As for children, I'm right there with you. I am going to be engaged soon.. (yeah your not supposed to know, but I've been with him forever and we've talked about it a lot.) So yeah I am thinking of children in the next few years.. I'm severely afraid of them getting sick. My boyfriend is just like you will just have to deal with it. Its not that EASY. He doesn't know that.. I actually opened up to my parents and talked about my emetophobia ( I felt like i was coming out of the closet ) But I jokingly, (but not really) told my mom that the kids will just have to go to GRANDMAS house when they get sick. ha.
But no really.. I just really want to tough it out because as much as it might suck when it comes to those times, I really look forward to being a mother..
