After 8 Years, Is this relationship with my Boyfriend love or just a safety net?

My Boyfriend and I have been going out now for 8 years. I am 25 and he is 27. Its the only real relationship we have both had. We lived together for 3 of these years abroad and things turned very sour. I became incredibly depressed and so did he, we became restricted in life and I feel I spent my whole young years looking after him, ensuring the rent and bills were always paid, and not getting to go out with friends. Last year I lost my job, I was supporting him as he returned to college three years ago. It became too much for me and I moved back home with m parents. I am still here today, no job, no friends, Im stuck, and yet me and my Boyfriend are still in this relationship and I don’t think either of us know where its going. Don’t get me wrong – we are both very good to each other we are nice and respectful, and well nice. We never fight. My Family often comment how lucky I am to have a nice Boyfriend but I cant help wondering: Is this relationship an excuse for not having the confidence to live my life truly or is it a good relationship because its safe and secure and sustainable
