What does it mean when a guy says "lol" a lot?

[Sheila]

I type "lol" when I'm texting and messaging automatically without even knowing I'm doing it so that might literally be what it is, a habit. I have friends who do it too even though it's not appropriate "lol" is automatic and you shouldn't look into it so much. Also consider maybe you get him to break up with his girlfriend for you, what's to stop him from just turning around and doing the same thing with another girl that he is doing with you right now? or even doing the same thing with his now girlfriend to be ex girlfriend while your his girlfriend? Think about it. You think he is going to change? Find someone better who is single.
