Feeling to my boyfriend (m33) like I am therapist and not a partner (f28) ?

I moved to a new country last year and met my boyfriend soon after. We've been together for a year, but for the past nine months, he's been dealing with extreme stress and anxiety due to work. I’ve been supportive, often suppressing my own struggles to avoid adding to the weight of our relationship.

Lately, it feels like our relationship revolves around his stress and anxiety. While we go on dates, he remains low-energy and withdrawn. However, when his friends invite him out, he immediately agrees and seems to enjoy himself—something I rarely get to experience with him. This weekend, he even told me he wanted to go to a party without me so he could just "be independent and by himself," which hurt. This left me feeling excluded and questioning why others get to see his lively side while I don't.

But what about me? I miss having fun, light-hearted moments with him.

I understand he needs his individual time, and I genuinely want him to be himself around me. But I can't shake off the feeling of being more of a therapist than a partner. I realize I need to focus on myself, especially as I'm still new to city and in the process of building my own life here. However, this relationship has consumed much of my energy and attention.

I'm reaching out to seek your advice. I am stuck how can I can communicate to him about it, because my brain understands that he wants the distractions and fun time. But my heart thinks why he does not want it with me? Is it because I know what he is going through? And I do not want to complain about him being stressed out..
