There really is no "ideal" timeframe Marisa. Some people say a full year, some say 6 months, but there isn't a definitive answer.
What's most important is that you can honestly answer to yourself that you are going to be able to handle the trials and tribulations of a relationship as well as maintain your sobriety at the same time. All relationships have problems and disagreements, so you need to be fully capable of dealing with them when they arise.
Having said that, one week seems very very early to me.
