My boyfriend doesn’t want to have sex with me

Recently my boyfriend and I haven’t been having as much sex as we previously did. He told me his sex drive has decreased but it has nothing to do with me. Although he says it doesn’t have anything to do with me it still makes me feel unwanted and unloved. He told me he still loves me and doesn’t want to be with anyone else but it’s completely knocked my confidence.

Any advice or similar stories?x
