Should I tell the dad

So I found out I was pregnant yesterday. Well I got a “false pos” the other week and two negatives so I thought I was fine but m, I’ve been feeling weird and nauseous asf so I took about four more and they all a BFP like in my face. Me and the father have been, fucking more or less but we have a good relationship and we’ve talked about more serious stuff but never really implemented anything serious. He’s a few years older and is ready for a family however he told me that even tho he loves me he won’t pressure me into anything especially a family. And this shit sounds weird but I’m trying to keep it as short as I can. Anywho, I don’t love him, I don’t even know if I have feelings for him, I’m truly in all types of confusion with my self and I have been for years hence why we only fuck. But now I’m pregnant and I can’t afford mentally, financially, emotionally, or physically, a baby. So I’ve been debated abortion or keeping it. But idk if I should tell the dad or not plus I been thinking about just cutting him off completely. Is that selfish? Just opinions and help please
