So a little background, i live with my bf (32m) and his family friend (67 f), she is super nice and caring and so is my bf, we've been together for almost a year. i'm having trouble with jealousy a bit. I get jealous when he goes upstairs and i can hear them joking and laughing together, when he doesn't invite me to go upstairs with him, or when he wakes up in the morning to use the bathroom and doesn't tell me he's going up stairs and hes gone for over 30 minutes. 

Side note, I'm not controlling at all though like i have no problem at all with him talking to his ex-wife about their divorce or him going out to see his friends or having female friends. I just feel like he is deliberately leaving me out? Like yesterday him and his (we'll call her aunt) aunt were talking about their families and grandparents etc and when i tried to chime in he literally spoke over me and changed the subject? Like im not trying to say he likes her more than me or anything but it just makes me feel like a trashbag, like he's sick of me.  
Any advice my peoples?
