<human>: Throwaway account obviously, 

Me [20F] and SO [23M], have been in a relationship for over one year, however it has began to start going downhill! He is an important part in my life but I few issues have been occurring that makes me wonder if these are red flag warning signs or is that what a relationship entails. 

-I'm staying with him although the I know he doesn't want to grow as a couple or live together or fully commit, he never even really wanted a long term relationship, we both want different things 
- I feel like a burden when I try talk or communicate with him, he never supports but instead critics and makes me feel a little more alone. 
- I don't know the list could go on but I am feeling rather upset 

What are your guys experience with a partner, what were some red flags you noticed? What is considered normal feelings in a relationship? And should I stay or leave . All I want is love, happiness and communication, and I feel like he is losing interest in me and isn't happy, and it's upsetting...

Give me a shortened version of the text
