So my primary partner and I have been having issues for about a year, at one point we were both dating other people but both of those relationships ended. We fight pretty often, we're not disrespectful or rude to eachother but we do bicker. There's pretty much no sex life anymore to be honest I think we are kind of sexually incompatible at this point. For a while me dating other people was enough to distract me from the fact things aren't going well with us but at this point we're kind of monogamous now because neither of us have had luck finding another partner. It's gotten to the point where like we seem like we are best friends who occasionally show affection, lovingly joke around/tease eachother, share an apartment and financial responsibility. Is this normal in long term relationships?
