I am being a real bitch to my bf of 7 years and they really doesn't know what to do and sometimes doesnt want to be around me . this is my first baby and I am trying my best to be happy and enjoy this because I want it , I just don't wanna push him away in the process . I just need some advice on how to help with the different things I'm feeling so I'm not so mean
