Don't know if this is my period talking or what

My boyfriend used to live with me at my moms house and things went south and he moved out well we are still together but I haven't seen him in 4 days and I told him I missed him and all I get from him back is yeah I'm tired he never tell me I'm beautiful and sometimes I just feel like I'm just kinda there. But I know that I love him I just don't think that he loves me as much as I love him and since he moved out I just feel like he's maybe talking to someone else or slipping away from me. We've been dating almost 6 months and this is my first real relationship so I don't know what to think or do about this situation :/
