I Think Failed Relationships Change People

My bf don't do anything for me... But he goes out of his way for his friends..he dont take me on dates ....but go clubs Friday nights n spends on his friends. Right now...I'm not sure what's happening..my bf doesn't make any effort.... And When I see a nice guy do kind things or just be pleasant...I find myself daydreaming abt him...i wont act on it though...omg.
