Boyfriend feels more emotionally unavailable, is it in my head? [30 M] [27F]

My boyfriend used to say a lot of intense things about me at the beginning. He couldn’t imagine life without me, I was the love of his life, I’m the most beautiful girl in the world. I felt so comfortable like he loved everything little thing about me and I felt so fully seen and completely myself. We could talk about our emotions and it felt like he fully cared about the outcome of this relationship would ask me for reassurance and get jealous.

We went through a rough patch where I was dealing w mental and physical issues and he became emotionally drained and I, because he needed space from my neediness (it was pretty draining and valid) and easily getting anxious and triggered (I’ve fixed this) during that period, I’ve learned slowly to not ever ask him for emotional support or express my needs to give him space.

Don’t get me wrong he’s a wonderful bf in many ways. He will ask me what I need and will do actions for me sometimes. He says he loves me and sometimes references the future but he can’t go further emotionally. He’s never called me names or anything like that. I see him looking at me lovingly sometimes and he’ll sometimes initiate physical affection.

And I appreciate all of that so much but at the same time I feel kind of alone and deeply craving that emotional intimacy where I can be myself and we can talk about our emotions where I feel like my soul is fully seen. The problem is that every time I try to talk, in a calm way, about wanting more of this, he’ll get frustrated and raise his voice or want to leave the room or leave early. Or he will say I just need to not be dependent on him and work on myself (and I do? But it feels invalidating bc I feel like it’s still valid to want a deep relationship regardless if I’m happy or sad). I just so badly and craving truly TALKING, expressing how much we love each other in words, being able to help him through his anxieties and him mine in a healthy way. I just feel awkward being myself rn and I don’t know what to do bc he won’t hear me out :/ he’s wonderful otherwise which makes me feel I shouldn’t even need anything else

Tldr: want emotional intimacy but not sure if it’s too much and don’t know how to get through to him
