What exactly does this mean?

This might be long. My bestie is a guy and he's super sweet to me. He never used to be and he would always make me feel horrible but I stuck it out and now he has claimed me as his bestie (he said it first) and says that were "quite close". I posted a question a couple days ago about something with us but I don't remember what it was lol. Every one tells me he likes me but I don't see it because I know he doesn't like me and I don't think I like him like that. But today I told him I was sad and he asked why and I explained that I just feel lonely and sad because I have depression and I always feel that way and that I felt unworthy of being happy. And we got into this huge convo about what I want and what will make me happy with myself and I said I wanted to be "happy, friendly, and lovable. But I don't think that will happen unless I have someone show me those things." And he said "you want a boyfriend." And I said "yes and no. I do but I don't want to add another person to worry about because I have a lot going on." And he said "I have a fix all...figure out what you want and take it." But it was weird because he was all excited about it. He's been Doing and saying weird things like that all the time and mostly about him wanting a girlfriend. So I said that Im not in a position to find someone right now and he said "what's holding you back?" I said that I was too unsure of myself and he said "you're stressing me out!!" So here's my question.

Why would he be stressed out about that? And excited that I want a boyfriend?

I also have some BQs cuz I like answering them.

BQ. What do you feel when you love something or someone?

BQ. Is it true that guys usually only become bestows with girls because they like them? (I asked that on my one question, I only got two answers so if you already answered it you don't have to!)

BQ. If you could choose one person to spend eternity with who would it be?

BQ. What's your favorite fruit? Lol kinda random.
