Am I wrong for this?

So my best friends has a bf and whenever I ask her if she wants to do something with me, she always invited him along and it’s getting really annoying. Like sometimes it’s ok but others I just want to be able to hangout with her and not her bf, cuz tbh I don’t even like him. Idk if I’m being a bitch or if I should just start telling her that I don’t want her bf to hang with us?
