Is there a difference between loving someone and being in love with them? Yes or no please explain your reasoning

Hubby and I recently welcomed a new baby boy but I have really been feeling like I'm not in love anymore. I told him this and he says he doesn't get why anyone would stay with someone that they don't love. I told him I do love him but I'm not in love with him.  He says it's the same no matter how much I try to explain that it isn't. I just as wondering if other people feel you can love someone without being in love with them.
