Quoting Cariad (SuperKink):" Maybe since you let your BD treat you like that your dad is just assuming that's your relationships sense ... [snip!] ... it for you? I'm sure if he realised completely that you do not like it, it's not funny and you want it to stop, he would stop."
And I agree with the person below...seems to be a deeper issue with BD, I'm an in your face kind of person. I wouldn't deal with that smurf. You definitely need to sit down and talk with both of them how you feel. If they continue to do what they've been doing then you should leave. You shouldn't be in a relationship that makes you depressed, it's not healthy for you or your baby.
