I love texts but the downside of it is that one can ignore and possibly delete. However, there is the advantage of the curiosity or the desire to find out what is contained therein in the text.
If you call, she might hang up. But sending a text can send the intended message. However, don't appear desperate or needy.
Let her know how much you love her and how much she means to you. Let her know you're waiting for her. After you send the text, don't bother her with another one. Continue on with your life. If she responds positively you're lucky. If not, you'll have to move on with your life. The reason is simple: you can't force someone to love you if she doesn't.
Well, you can call her. If she picks up start with greetings then ask her if you can meet to talk when she's free. If she accepts, good. If not, send her a text message.
