Sharing TAXES

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.
