My boyfriend won't tell his family we are back together ):?

so to make a long story short I am 27 and my bf is 36 years we been together for 5 years old. he was rasied by his grand mother and he did not grow up with his sisters but they are working on being close. and starting a relationship so lately we been going through problems and i found out that he been talking bad about to his family when we broke up and got back together he won't tell his family that we are back together it's like he is embarrased to tell them we are back together. even though how many issues or times we broke up I never have a issues telling my friends and family that we are back together. so last night I called him and i heard his sister in the back ground and I heard him tell his sister the crazy girl is calling me so i said ima call u back because I don't want to be rude and his sister said out loud that i'm always rude keep in mind i never even met his sister i really think he was talking **** about me

to her. I hung up the phone because i was so hurt that he preferred to me to his sister as that crazy girl is calling he didn't he say it's my gf and he didnt even call me back because i know she probaly told him to stop talking to me. I love him so much and I don't know what to do. he's a virgo and I am pisces if it helps
