My straight friend is unable to help himself and I have some weird feelings

His wife passed very recently. I was supporting him before the passing and after that. I would cook for him, or constantly invite him for dinner. He won't cook, he doesn't care. He just stays hungry (unless you give him food, it seems as if he doesn't care to eat).

He sees a psychologist which I'm sure is beneficial but the trauma is too recent. He either cries or just walks in the house all night (did I mention he just came to my house and decided to stay?). I always loved him and I want to support him because he's a really good guy and is having an awful time.

I was never into them. Maybe when I was in my teens but that was more than a decade ago. Other than he's just a dear friend. But now that he cries, that he's all day home and he needs hug something changes. It's not sexual. It's a huge trigger that he needs me to protect him and it makes me feel like he's my bf. I don't know if it's clear the way I put it. The way he acts makes me wanna kiss me because he's closer to me, he's inside my personal space and this causes this reaction.

My approach is to just ignore these feelings because I need that his well being is in distress and that's all that matters.. but I've got nobody to discuss this and I'd appreciate your thoughts.
