Is my marriage over?

Me and my husband are going through a rough patch. For a few years now... He doesn't say he loves me anymore. We don't have sex anymore. It's been 7 months and we haven't had sex. He doesn't even want to engage in actual conversation with me.... I try and he gives me dull monotone answers. My sister was over and talking about my marriage quietly with me. My husband walked through the living room in a huff and she said "He's not happy honey. Your marriage is over". I started to cry asking why she said that and she says "Honey he's in a bathrobe at 3 in the afternoon. He's not happy". I don't want my marriage to be over😢😢😢😢
