Guy Friends???

Okay, this is a bit of a rant. Why is it that the moment you're having relationship issues, or your friends find out you're single, they immediately become EXTRA friendly with you? Like, I had a day where my friend, O, had helped me contact my ex. I needed a bit of closure, which I didn't at all get and instead it turned into an argument (very one sided). However, O was in a call with me and comforting me because I was SOBBING. Later, we ended up getting into a deep conversation and we reflected on our friendship and life and shit. Dude. He decides right then and there, knowing fully well I'm still hardcore holding onto making things up with my ex, that it was the best idea to explain how he had a crush on me for a while now. We had tried once before in 8th grade, but it never made it past the talking stage because he had made me really uncomfortable and I decided it would be best to just... not. Anyways, he mentioned that he wanted to say it in the moment because otherwise, he knew he would never get the feelings out. Cool... but was that REALLY the right time to mention it? I told him that I wanted him to push aside those feelings because I needed a FRIEND. He told me he understood, and we continued to talk. I later mentioned that I didn't think I should get into any relationships for a while, not like I'd even want anyone BUT my ex. He mentioned that it kind of hurt that I didn't want to get into any but that he understood. I brushed it off until we were saying our farewells for the night. I mean, I was hella tired and it was late. He said he wanted to keep talking to me but understood that I was tired. Then, he continuously mentioned about how if I ever wanted to be anything more, we could. I said goodnight and left the call. I ended up blocking him the following morning because... that entire interaction made me genuinely uncomfortable, especially because he KNEW what I was going through. Keep in mind, the only reason why I became friends with him again after 8th grade was because I had already known him since 4th and he was part of my friend group. I had noticed he changed and decided it would be okay talking to him again. He had been helping out with my ex and my problems for about a week before he confessed. I felt comfortable talking to him, but I had NEVER expected that.

Another friend of mine had reached out yesterday. I had known him for about 4 years (online) and we're pretty good friends. I know he's been going through his own relationship issues and recently broke up with his girlfriend. We hadn't REALLY talked for a good few months, but it's one of those friendships where we could start talking again out of nowhere. See, I'm not entirely sure he wants anything more than to be just friends, but he's been acting a LOT more friendly than I'm used to. Last night, he had asked to sleep on call, and I said yes because he's my friend and he was having trouble sleeping. I honestly didn't think much of it until one of my friends mentioned that it's usually a couple thing. After we got on call, he said "I love you man. Goodnight," through text.  The next morning, he greeted me with a good morning and a "Thank you again <3." The heart threw me off a lot. A few hours ago, he randomly told me about how proud he is of me then said that he could go on but didn't want to make me uncomfortable. I told him I'm not the greatest with compliments/positivity (I usually only take them well from my closest female friends and my now-ex) and he apologized. I told him it's okay and then he later mentioned that he thinks I'm pretty. Maybe I'm just overthinking the entire situation, but it feels kind of weird coming from him. I don't want to stop being friends with him though, especially because I do care about him and he's going through a lot. I'm just worried. 

I wish people got that randomly becoming overly friendly towards someone who JUST got out of a relationship feels really... weird. Maybe that's just me, though </3
