Dream Interpretation. About Sister & Boyfriend!?!?

[SMACkS]

So I had a dream that my sister and boyfriend had sex & my mom saw and she was mad, an I was like I don't want to be with you anymore (to my boyfriend). An my mom was like if you don't want to be with him anymore theres no harm in him being with your sister since they already 'did it'. I was so hurt & neither of them were tryin to talk to me..he didn't even care if it was over... I was just wondering does anyone kno what this could mean?
I trust him more than I've ever trusted any man in my whole life, In other relationships I DID have gut feelings and they were always right. but with him I dont have a gut feeling. & no I'm not jealous of my sister lmao there is NOTHING to be jealous about. & the possibility of them being together is highly unlikely.. we live very far from eachother and neither have their OWN transportation.

#possibilities:

You don't trust your boyfriend
OR
You couldn't bear to break up with him

You're jealous of your sister
OR
You feel that your family (in general) don't take your relationship seriously.

That's all I got.
