What's going on with him?

[Wheresthechill]

I've been talking to this boy for a while, and we're really good friends. He's always been sweet to me and we can pretty much talk about anything. Sons thing about him is different and I really like him as a friend.
Lately, he's been acting a tad different. Like the other day he sent me a picture of him and a couple girl friends and I had no problem with it. But when I responded with a picture of me and another guy friend he responded with "..Oh"
In fact, whenever I talk about another guy he gets really whatever and changes the subject.
He also asked me if I was a flirt because he's not "with it" and is ready to "settle down"
This confused me because that's something you ask/say to your crush, not your friend.
Today he asked me to stay home from school because he was staying home and wanted someone to talk to (I stayed home because I had an orthodontist appointment and my mouth was hurting too much. My staying home had nothing to do with him). We were talking and we decided to play 21 questions and I asked him if he could kill anybody who would it be, and he completely changed the subject and just asked me who was the last boy I kissed. I answered, and of course he said "..Oh."
He also even saves the videos and pictures I send him because he thinks I'm cute and that I'm funny and have a nice voice. (He's not a creep or anything, I even do the same)

My question is just what's up with him?
And does it sound like I like him?

I don't think you like him, no. Also, he sounds like a huge creep to me. Sending every red flag alert inside me. Have you ever met him in real life? Skyped? He's sending across that he likes you, and sending it very obviously. If you've never live video chatted with him or met him in real life, even if he's sent you multiple pictures it could just be of some random kid he found on facebook. He sounds like a creep to me.

Lol, yes I've met him. He's not some random guy I began talking to on the internet, he's a friend that I met somewhere I can't remember a while back, but it's just that we've been talking the past month. We FaceTime and everything.

He's obviously interested in you (more than a friend), but he also seems to be quite jeaulous and not having a good sense of "understanding the other part", if you know what I mean. He's jealous because he doesn't want you to be around other guys, and he also con't see that you could feel unconfortable if he sent you pictures of him with other girls. About the question he didn't answer, I guess he would like to kill the guy you were with in the photo you showed to him. He might also have lack of confidence and low self-esteem, as he's thinking other people would steal you and he couldn't do anything to stop it.

If you like him, I suggest you go for it, but keep in mind that a relationship is based on trustworthiness. If you think he doesn't deserve you, I guess it's better to stay only friends, but he really seems to like having you around.
