Does he love me or is he lying?

The guy I’m dating says he loves me and cares for me deeply but he never messages or calls me on a regular. We spend a night together and he don’t even follow up the next day. He doesn’t even message I normally do but I’ve stopped now and since I’ve stopped not once has he done it. Don’t know if I’m just wasting my time because when we are together he tells me everything I want to hear but when we are not he disappears? Not sure if this man is using me or what pls can someone help a sister out
