Is my boyfriend just using me?

I really have always loved my boyfriend badly like we're 2½ years into the relationship want to marry and all and like one day my sister's boyfriend informs me and my family that my boyfriend had said some fked up shit about me (like about my looks, our family's money and sexual status etc) but like my sister's boyfriend is a bit sly so i let it go.. But I'm more wary of my boyfriend and careful

3 months later.. My boyfriend is kinda starting to be really weird.. He indirectly asked me if he'll get any shares in my family's company and like that's so unlike my image of him and like i don't even know what to think coz it's literally that he does ask me a lot for money and im still not sure about how deep his love is because he does act like he loves me but lacks that passion

And overall I'm so confused?

Is my boyfriend just using me?
