A married man gave me a cup of coffee this morning.

A married man sends you a cup of coffee and 75 expressions in the morning, which may mean that he has some affection for you, but it doesn't mean that he wants to develop a relationship with you. This behavior may be that he wants to say hello to you in a polite and friendly way, or to express his support and encouragement to you.

In this case, if you don't feel the same way about him, you'd better be polite and keep a proper distance so as not to let him misunderstand your intention. If you want to build a deeper relationship with him, you need to be very careful and respect his marital status, and make sure that your actions will not hurt his family.

Generally speaking, the meaning in this case may vary from person to person, and it is best to understand his real intention through further communication and exchange.
