Boyfriend issues🤦🏽‍♀️

I feel like my boyfriend just doesn't want me anymore. He tells me he's in love with me and he loves me and likes me but his actions show otherwise. And when I ask him if he wants to be with me he says I don't know but than will end up saying yes and he always says he'll never leave me but I'm scared and don't know what to do because sometimes he'll act like he loves me and I'm all he cares about and others he'll pretend like I don't exist and he doesn't want to be with me
