relationship help

i usually never come to this app for any kind of help but i have no one to help me out here. i have a girlfriend of almost 10 months who is an amazing person and is the sweetest person i have ever known but lately i have been feeling like this isn’t a relationship that is one that i want (regularly don’t want any kind of romantic relationship) and also can’t seem to see myself in any serious relationship later down the road, i really do love her but have found it harder to be there for her because of this feeling, but my main issue is the fact that i feel stuck where i am, i want to be independent and free but she relies heavily on me for her emotion, mental and others, in short i have a small feeling to leave but it is very hard to due to my care for her and her poor mental health that she heavily puts on me, any advice or suggestions help, i am open to anything
