Help what should I do ??

So i started going out with my boyfriend two months ago, and mehn he never calls me for shit for the last 3 weeks .... ever since he started his new job,

He never calls or text me good morning or goodnight he will read my text and not respond and he doesn’t make a big effort to see me :( he didn’t even tell me bout the last day he had off I found out after I finally got ahold of him. Should I Jus see this as an adult adult relationship and jus not care lik that that he barely talks to me or should I do something bout it ? Because I don’t see the point of dating someone if we don’t talk regularly and try see each other whenever we can :/ please please help me I’m not trying to keep falling in love just to fall out again. I’ve only have 4 bf and my last one was my high school sweet heart who cheated on me constantly for 3 years , so I’m so lost . I need my fellow females sorry this is so long.
