My bf doesn’t text me

So my boyfriend and I used to talk quite a bit over text and the phone before we dated/at the start of us dating. We’ve been together a little over a month now and the past two weeks we barely talk. Like it will get to be 6pm/7pm and I’ve yet to hear from him and if i wanna talk I’m always the one to reach out. How can i talk to him about this? Or am i overreacting? We only see each other once or twice a week so not much at all because we work and go to school but when we’re together everything is completely normal. I feel annoying when i text him because i just get left on read or he just doesn’t open it period
