Need some relationship advice plz desperate 😳

Can anyone give me a bit of advice please. Sorry in advance this is long.

Ive been with my boyfriend for 5 years. & have known him for 7. I have a 6 year old who sees my partner as his dad & always has & always will. They have a really good relationship which i would never break for them.

I love my partner with all my heart but feel like i need more from the relationship. We have been trying for a baby for 6 months which is something that was discussed & is something we both want. However i am currently staying at my mums with our son splitting his time between us both because we had a massive argument & i walked out. My boyfriend basically told me that he 'saved' me & that he pretty much done me a favour getting with me. & said that if i want to get married then hes not the person for the job. Which confuses me because he asked me to marry him 2 years ago but since then never got me a ring or talked about moving forward with this commitment. Now, i love him & dont see why its so bad that i want to marry him & be his wife. But i also dont want to be with someone who says he pretty much done me a favour.

I dont know what to do or how to move forward with this. He has become so complacent & just sits in the house with films on & on the ipad looking at stuff hes interested in. I want fun & memories & date nights but whenever i mention something hes not interested or he does it & is miserable all the way through. I know we both have to try but i feel like its always me trying & hes just not interested & i feel partially thats because he doesnt really love me. I asked why hes with me and he couldnt give me a good or nice reason why hes with me. He said this was cause he was angry but im guessing its cause he cant think of anything to say because hes got nothing. I want to talk to him about this but cant because i feel ive made my bed & should lie in it. But i dont want to lose him if theres something i can do to compromise..

Any help or advice would be much appreciated. 😢
