Ultimately, the most fulfilling choice is the one that aligns with your values and brings you happiness. **

Casual relationships are non-committal, often short-term connections between individuals who are not looking for a serious commitment or long-term partnership.

Casual relationships can involve activities such as dating, hanging out, or engaging in physical intimacy without the expectation of exclusivity or long-term commitment. **
