Emotional detatchment

My partner of 4.5 years that just broke up with me has said that he has been feeling detached from me.

I pressured him into marriage when we both weren’t ready , I guess I just liked the idea of marriage with him l. I still want it , but understand it has to be a mutual level of wanting and connection. Everything was fine up until I wanted it so badly . We’re 23 this year , we’re young and I understand his POV. He has expressed that he felt it was early and that he wanted to achieve things with me first before marriage.

Can we ever fix that feeling of detachment ? I don’t feel the same but he feels it . If we give it another chance does anyone think he can love me again , he said he still cares about me and loves me but he is confused with it and believes he can’t give me everything when I deserve the world and someone that will , but I know he can because we use to talk about it all the time and make plans casually - it’s the fact that I pressured him about it. He believes someone will give me better but I don’t want anyone else

Please no nasty comments I already understand I’m a horrible person

Thank you 💛
