Should i text this guy? Or no?:/?

So ive literally been talking to this guy everyyy day for 6 weeks straight. We both like each other, and flirt a lot when we do talk. He normally is the one to text me but like once a week ill be the one to start the conversation. Saturday he didnt text me all day, so i decided to see if he would sunday, he didnt again, so i texted him, and everything was fine. Now its tuesday and he STILL hasnt texted me first, which is really weird for him.. Should i text him tonight? Or just not bug him.. Cause what if hes losing feelings?:/
