Clueless

I still don't know if a guy is into me. My friends or mom will say yeah that person is totally into you and I would have 123455 arguments why that isn't the case.
My question is how do I know?
Also, how did you guys shoot ya shot/ get/met your man/husband?. 
P.S. One time I actually thought a guy liked me because he was asking a lot of personal question and was always friendly but he didn't like me and he has a girlfriend😂😩. I'm telling you I'm waaay off.
