help asap!!

Am

so me and my boyfriend have been together for just over a month and its been amazing, i really like him, and just before my holiday we got a bit hot and heavy and he fingered me for the first time and i felt good about it until now because he’s barely texted me the entire week i’ve been away and when i asked him if he missed me he said “yh” then said “jks nah”.. before he would text me constantly all day and he hasn’t text me all day today which is so unlike him 😣 he’s been smoking weed quite often too and idk how i feel about that either. honestly just don’t know what to do as if i ask i feel like i’m being irritating and needy :( plssss help x
