facebook friend the hell is going on with him he was talking for a while to me then quit?

what does it mean when i looked on my friend s profile in their friend s list, everyone that they have as a friend saids "add friend" but my name has nothing beside it even though i added them and they accepted my friend s request, so what is going on? plus where there s suppose to be a profile pic of the person that "read" the messages, it doesnt show it at all.

i dont know what is the "problem" of not understanding what i asked, i have a friend, he accepted my friends request on facebook, but he doesnt message me on messenger & he doesnt comment through posts, even though i can see his posts and it shows that he's online, but he hasnt blocked me cause if he did, i wouldnt be able to see anything from him. i want to know why he's not responding cause it seems odd cause we talked for a while.

If Im Reading this Correctly the way you have it Worded is a little bit Confusing
