BAH ???

Long story short... he still asking me for money for bills when bah covers it ... our bill is never 900+ he’s sending money to his family & making me pay bills when I’m not working 😳 .. my family helps me because I’m pregnant and high risk ... what can I do ?? His mom name is on all his accounts & what will I do when he gets deployed ?

UPDATE: went on base & spoke to nearly everyone & they said they can’t help because I’m a civilian & they can’t make him pay anything... they can only tell him what he needs to do .... oh & he moved out I guess & now every time him comes to the house a sergeant comes with him & to my appointments ... I believe he’s working on a divorce because he’s selfish & his mom is money hungry ... either way his loss
