I am grown. Why won't they just mind their own business?

My Sister, mom, Friends etc keeps on saying im dumb for getting back with my ex boyfriend because he had a baby on me and then cut me off when i lost my Job back in July 2023. They said im slow for allowing him to come back into my life after i begged them (my mom and sister to live with them because i was living in my car with my daughter) my sister asked me why i get back with him when he left me homeless that she was the one who got me a job to provide for my daughter. Like okay? Why can't they mind their own business? I love him still and THATS why. Plus i don't want him getting back with his so called baby mother anyway. Im sure he's a changed man.
