Crush issues

So my crush talks to me in person which i'm cool with. i like talking in person but, when we text its really not for long. it kind of gets awkard for me because when i talk to someone first i feel like i got them at the wrong time and start to over think things. i'm the type of person if you talk to me first i'll talk to you and be cool with it. but when i have to talk to you first i just feel some type of way about it. but in school she would always be the one to talk to me and i talk away but, i don't know. What should i do?
