Am I a bad person

I don’t have a job. Got fired in November but I was working for a while before I got fired so I will be filing taxes. Do you think I’m wrong for telling my SO that I wouldn’t give him any of my taxes? Yes he works. But he won’t be getting anything back. He’s been doing everything that I can’t do.but I feel like he know that’s my only big lump some of cash and for him to ask me to give him some of it is selfish. Of course I’m going to get him stuff but I was thinking that I wanted to save as much as I can so I wouldn’t have to constantly come to him for anything I need or keep falling short on my bills and having to come to him. Only going anon because if that is wrong I’m embarrassed. 🌚 no we are not married but we do live together and have a child together. Been together for 3 years on the 26th. Please give me your honest opinions. Thank you.

EDIT: Thank you everyone for your answers. The only thing I’m always short on is my probation. And phone bill. I told him I will take my self off of the family plan. I dontreally care to have my phone if I can’t pay the bill myself. My son is always with me so there’s no need for it. Everyone know where I live so... and we both get SSI he gets one for him I get one for our son. I pay my half of the rent with my sons check and my car insurance then I go pick up little things that my baby may need. So in reality thenonlything he really helps out with is my phone bill... personal items I may can squeeze in with my sons check and I also babysit on the side.
