Usually very little. For a lot of people "lol" is not a laugh at all. It is punctuation, a way to make a short text sound friendly instead of flat.
So the word is not where the answer is. If you want to know what his "lol" means, look at what he does around it, not at the 3 letters.
Free to try. We never store your chats.
"What does lol mean from a guy." "Is lol flirty." "Is lol a dry text." The lists give you 6 meanings and ask you to pick 1. That is guessing about a man you have never met.
Some guys put "lol" on every text they send, to everyone. Some guys almost never use it, so when they do, it is doing a job. A list cannot tell you which one you are texting.
For most people who do it, "lol" is a softener. running late lol. work was long lol. It takes the edge off a short text so it does not sound annoyed.
Scroll up. If "lol" is all over his side of the chat, with you and with everyone else, then this "lol" is his normal. It is not him laughing at you, and it is not a sign he lost interest. It is just how he types.
Look at the same week, not the same text.
Say he sent "lol good" after you told him you got home. On its own, that can look like nothing. Most people would read it as "he is bored". Now look at what came before it that week:
That "lol" meant almost nothing. The pattern meant everything. 1 text is not the signal. What he keeps doing is.
It works the other way too. If the plans stopped, the questions stopped, and now every reply is "lol", the problem is not the word. It is everything else that went quiet.
It lands on something serious. You told him something that mattered to you, and he answered "lol". That is different from "lol" after a meme. Some people laugh when they do not know what to say. Some use it to skip past a hard topic. Which one he is shows in whether he comes back to it later.
It is new for him. If he never used to write it, and now every reply is "lol" and nothing else, the change is the message. Not the word. The drop in effort.
It is the whole reply. "lol" alone, after a question you asked, answers nothing. "lol yeah friday works" is a normal yes with a softener on it.
Do not ask "why do you always say lol" or "is that all you have to say". It turns 3 letters into a fight about nothing, and if it was just his habit, he will not know what you mean.
Answer the conversation, not the word. Keep it easy, and give him something real to answer. Something like: haha ok. still good for friday?
If his "lol" landed on something serious, you can bring the topic back once, calmly, without pointing at the laugh. How he answers that tells you more than the "lol" ever could.
Not every "lol" needs a reply. If it closed out a small conversation and nothing is left open, you can leave it there. Answering "lol" with a paragraph is how a quiet night turns into a night of rereading the chat.
If "lol" is part of a bigger pattern, where you do all the asking and he sends 3 letters back, another message from you will not fix that today. Let the thread rest and see what he starts on his own.
You paste the conversation and it reads "lol" against him rather than against a list — whether it is his normal way of typing, what he has been doing around it, like texting first, making plans and following up, and whether any of that has changed.
Then it writes the reply back in 4 tones, and tells you if the better move today is to wait instead of sending anything.
