I feel lost please help

I feel so lost anymore. My boyfriend use to text me as soon as he got off work now I’m lucky if I hear from he at all anymore unless I blow his phone up. He doesn’t act like he used to anymore . I know he’s not cheating . It seem like he doesn’t want to put effort in our relationship anymore . We have been together for a year and almost five months . I don’t see him every day because he works out of town. So I’ll see him on the weekends every two weeks and sometimes I’ll go up there with him. I don’t know what to do anymore .
