Boyfriend's sister being a thorn in our relationship???Any tips on how 2 make B.F. pay more attention 2 me?

you are 26,but you are talking like a stupid kid...you've been with him hardly 6 months..she is his sister, i mean blood relation..feel good that what he had done to her after they lost their parents...feel proud to find someone like him...don;t ***** complain about thier relationship,she deserves to be treated well...don;t expect everyone will survive on their own,few people need support from family.
