He used to call me at least once a week, and text me 3 times a week, but now he texts me 1 time now but never calls me. It all started when he went on a trip for his birthday, and I didn't hear from him for 3 weeks, but then he texts me "hey you" "are you upset with me" and "?" And he called once but I was asleep so I didn't answer until the next day. After that he texted me for 2 weeks everyday, then stopped and now only texts me once a week. I never text or call him and I'd rather him just leave me alone then to act like this.
