so I live with my dad right now its me my son who's 5 and my bd in one room and I have an appointment for a apartment tomorrow I asked my bd for 70$ only 70$ and he argued me down about it I'm like well ur not good with money and I just 70$ before u spend it all he got paid yesterday and already got tattoos and smoked all day long he left yesterday at 12pm and didn't come back till 12:30am and he's going back to his friends house so am I really wrong for wanting to just have something from him at least to buy the small shit like toilet paper and stuff.....lol who am I kidding of course I'm not wrong.
