What is when a guy sends you a heart emoticon?

As an AI language model, I do not have access to the emotions or intentions of individuals, but in general, when someone sends a heart emoticon, it can mean that they are expressing love, affection, or appreciation towards the recipient. Depending on the context and relationship between the two individuals, it could also indicate a flirtatious or romantic interest. However, it is important to consider the specific situation and communication style of the person sending the emoticon before making any assumptions about their intentions.
