Taking MY Money.

Tayste
I just got paid today, I work part time and get paid biweekly at minimum wage. So as you can imagine, my paychecks sort of suck. I got paid 290$ today but my account was 14$ negative so that got taken out so I was left with 276$ to last the next two weeks. I, alone, could live on this just fine but seeing as I have bills to pay and am attempting to save money for my baby and save a little outside that for my shower, it's kind of tight. My mom wants to throw me a shower but she lost her job and can no longer pay for it, so I'm getting the money together bc there's no way I'm letting her borrow the money from her boyfriend (I feel like it isn't his responsibility to pay for it). But my fiancé has my bank card to put gas in the car on his way home from work today. He spent 16$ at the gas station, 10 in gas and a pack of cigarettes (my guess) AND THEN I see that he WITHDREW 50$!! I know it's not a lot but it left me with 200 and something. And I have no idea what the 50 is for. He's not home from work yet so I can't ask him until he is but I'm so upset. He used to have a problem with drugs in the past and that's what I'm afraid he's using it on. 😓 advice would he appreciated on how to confront him without accusing him of anything and making him angry!
