Sometimes a lot of the anxiety that people have in a relationship is from not talking or asking questions. You could drive your self crazy with all of the questions. Does he like me? Does he want a serious relationship? Does he like how the relationship is now? ect. Be open, ask questions. You said something about him texting you while he is at work, well tell him that. Tell him that you like it when he does things like that. But just dont stress to much about the relationship and just let things take there natural course. Dont be afraid to ask him questions and to tell him how you feel about things also.
