Should we break up?

My girl and I get along relatively well until it’s time to start talking about emotions or feelings. We’ve been together 6 years lived together 5. We have sex 3 times in the last year, it’s been on the decline for about the last 3 years. I literally can count how many times we had sex. She is affectionate and holds me etc. it just seems like she doesn’t like to do things with me. When it’s with others she has a great time. With me she’s checking the watch. She drinks all the time not a drunk. But when I say let’s go have drinks she will go but then orders a drink and doesn’t drink it. At home she acts tired and had to be up early. When invited out it’s no problem. Idk what to do am I dumb for just standing by
