What dose this mean im so confused?

if you don't txt a guy that you like. like are you trying to find out if he is interested in you or something? because there is this girl that i asked to prom and it hard for me to tell if she likes me back because she never txt me like at all i have to txt her and i don't a lot only sometimes at night this has been going on for atleast a month now. but she also kinda shows signs that she like me. once weekend when i was going to go hang out with some of my friends and i was kinda staring to blow them off then she called me. so i think she was trying to hang out with me because she dosent go out alot. also when i met her mom when i was gettin my tux and she said she's heard all about me. it might be because she fells like im useing her for a date but it could just be that she dosent like me. i wanna ask her out but i dont know because i dont want to make things weird. its tearing me up inside(also how should i ask her out if i decide to)
