Feeling alone

I live at home with my parents. My bf lives with his parents as well. I usually stay and sleep over there and come home during the day when i dont have work. I feel like my bf and i are not really connecting. When im with him i feel alone because he is always occupied with something or someone else. We dont kiss much anymore unless we are having sex. I have tried talking to him about it but i dont think he sees it. He thinks because we are with each other everyday and spend time together that everything is fine. I come home and i have no one to talk to here either. My dad is never home because he is at work and my brother is usually occupied with video games or on the computer when he is not at work. My mom is really hard to talk to. She tends to get an attitude when i try talking to her about stuff that is going on in my life and we end up in arguments because of it. My dad is the person that i can talk to easily at home but like i said he works alot so i dont see him often. My best friend got married and ever since she has been hard to talk to. I text her and never get a response until a month later. Even then she still doesnt text back after i reply to her texts. I feel like im going crazy with no one to talk to in my life. I really feel alone.
