blitzbabe, your snakes will be okay on one pinkie a week until they can move up to fuzzies. Just don't expect to see the same growth that people who are feeding more do. If you want to feed more without making a big change, you can feed them a pink every 5 days. There's no real reason to feed multiple pinks in a meal instead of moving up to fuzzies. I would feed a two pinkie meal once or twice, just to make sure they can handle it, and then move them up to fuzzies. When you notice that there's not much of a lump from one pinky, it's probably time to try this.
There are lots of reasons not to house two snakes together. Cannibalism is rare, but does happen in corns. Also, if one snake gets sick, your other one will probably get sick too. Likewise, any parasites will be shared. One snake may be more aggressive, or one very shy, and one or both could be stressed due to living together. If they are male and female, they will probably breed. Breeding a female before she's big enough (~ 3 ft., 300 grams) can result in egg binding, which can be fatal. Even if it's not fatal, you will end up spending lots of money at the vet and your poor snake will have a very rough time. That said, some people do successfully keep two snakes together. It usually works best with two females (or so I've heard, because I've never actually kept two snakes together), but even then all the above risks are present except for breeding.
Alex Dew, it looks to me like you are just begging for that female to breed before she's big enough! And they do not "love each other" ... they may curl up together in the same hide because that hide happens to be at their mutual preferred temperature or location.
