"Get a sweetie" is a phrase that is commonly used to express one's desire to find a romantic partner. However, there are plenty of other synonyms that can be used to convey the same sentiment. These include phrases such as "find love," "get hooked up," "settle down," "fall for someone," "connect with someone," "start a relationship," "court someone," "woo someone," or simply "get a girlfriend/boyfriend." Each of these phrases can be used in different contexts and can have slightly different connotations, but all in all, they represent the same basic idea of searching for a romantic connection with another person.
