Relationship crisis

I’ve been with my boyfriend for 8 years now. He’s told me he dosent want to get married because it’s just a piece of paper. This past may he gave me a ring and we agreed we would be engaged for awhile before getting married. He tells his family that he wants to work on his self and the relationship before getting married. This past week he told me he dosent want to get married so I took the ring off.. I’m confused and don’t quit understand what’s going on. We just had a baby together and he is a father figure to my older boy. So I’m just wondering if I should stay or just cut my loss. I’ve been with him for 8 yrs and do love him deeply. Wat do I do.
