I need your help, my partner is having depressive episode, i don’t know what to do.

Me (33F) and my bf (29M) we are just 3 months in relationship and last week, he texted me he is not okay and wants to isolate.. Then I gave him space then i checked in on him 3 days after, he told me that he feels heavy, emotionally drained and burned out. I told him I will be always available if he needed me. Then after a day he replied he wants to be alone and he might go in with therapy. He told me i hope I understand if he wants to be alone. I agree with him seeking professional help and still I’m not going anywhere.

I love him so much, i dont want him to leave me.

What should I do to show my support and love?
I want to see him, it’s been a month since I saw him because of my business trip.

I want to go to his home and hug him but he said he needed space
