drama queens monopolizing my husbands time and attention, any advice?

I have an issue I would like some feedback on.

My trucker has a sister ( 43 yrs ) who just left her boyfriend and entered a new relationship and he also has an adult daughter of 27 yrs.

Both of them seem to want to monopolize his time both over the phone, texting and having him stop by on his trips ( which results in longer periods away from home ). Sometimes we will try to go out for dinner or lunch and he spends most of his time texting them while we are out.

Now I am not a complainer by nature and certainly am not as dramatic as the both of them; therefore... not demanding. These two seem to want him to be their sounding board and Mr. Fixit for their personal issues, which kind of leaves me out of the picture .

I tried to bring this up to him but he thinks I am jealous of the time he spends with them and thinks I am overreacting and possessive.

Any suggestions? Hervy???? Is blood thicker than water? Am I just water???
