Search Results: signs a guy likes you signals

So this may be obvious but I am trying to figure out if this guy in my class likes me-he has been giving me mixed signals. I just recently became single and I am wondering if he just didn't try anything because I was taken. I am almost positive he is a shy guy. Here’s the signs:

Good Signs:
• If I catch his eyes from across a room, he looks at me and will sometimes quickly look away
• Blushes when I talk to him
• Listens to every word I say and responds when I am in earshot
• He was telling our group today about a friend (girl) he is going to visit in california but quickly looks up to me and says it is a group of old friends and mentions a lot of people are going
• Looks to me to be laughing when he makes a joke in class
• Checks ALL my snaps
• Agrees and likes everything I say I like
• Last weekend sat as close as possible to me at a party the whole night-touching at one point
• If I ask for help on anything he doesn't hesitate
• Leans in when he talks to me
• Gets jealous or immediately interested when my ex comes up in convo
• Stands near or body facing me when I am around
• Gets quiet when I am around, is normally pretty loud
• Gets nervous around me

Bad Signs:
• Recently hasn't made efforts to hang around where I am at school with our group of friends
• Doesn't hardly initiate text conversation out side our group chat
• Hasn't been as joking with me as he used to be in person and in group chats
• Doesn't send me private snaps, only group snaps
• Doesn't sit next to me in class and almost seems to avoid sitting next to me
• Seems to avoid the group text conversation as soon as I say anything in it
• Is always on his phone when we are alone- like he is trying to avoid talking to me or is too nervous to. Not sure.
• Doesn't watch me or look for me in class (yes we can see out of the corner of our eyes guys) as much as he used to

Sorry I know this is long but please read! I known this guy since 7th grade and now we are freshman's in High School. He only dated this one girl in 7th grade. When I first met him for the first week I had a crush on him already till now. He is the smartest guy in our grade level, nice (most of the time), cute, popular and really outgoing. We always have classes together but this year we only have one class. At the beginning of the year when he walks into the classroom he has to walk over to my desk and he kinda tap it slightly, once he didn't tap the edge of the desk but the back of my elbow but it was really lightly that I convince myself it was an accident. But recently I have been talking to a friend of mine in class and it was on guys and she likes this guy and i told her who I like..(he sits one seat across from me) and I think he either knows its him or thinks that I like someone else. Anyways after that he stop taping the edge of my desk and I feel like he stops noticing me... what does this mean... did he knew that I like him or he thinks I like someone else. Plus what were the signs of taping? Or is that an accident? I feel like I get mix signals from him time to time! please help me!! What should I do. I know this is long but I haven't like anyone this long!
