Polls: Dating

I have been corresponding with this guy I met online and talking on the phone for 3 months. We went on a date last Friday and things went really well I thought. After dinner we went to his apartment and he played the guitar for me and sang for me. We talked for a couple of hours and cuddle and eventually kissed. He told me hr felt we were on track for more dates and hopefully make things official. He asked if we could exclusively date each other through getting to know each other. After the date he texted me saying he wants to make us official soon as he didn't want to lose me. A day or so after that he has been really quiet. I know he had to travel with work but he hasn't texted at all. I texted to say hi yesterday and he responded to all my texts and said he was thinking a lot about me. Today i didn't text at all and i haven't heard anything back. I asked him if he was still interested and he said of course that he is just super busy.
I am worried he is just giving me excuses and he doesn't really like me.
He was all over me when we met in person. What happened?

So I met this guy on Tinder ( I know, not the best place to find love...) but we talked a lot etc Clearly to me he wasn't the douchebag type and so on. He asked for my snapchat which I gave him. The number of snaps really depended of the day. Sometimes it was just a few or nothing but on other days we could send each other at least 20 pics. He proposed to go running with me or studying or watch a movie etc. but we couldn't because we had our exams first. It also became our habit to send each other some 'sexier' pics but it never went overboard (by this I mean fully naked or lingerie or showing boobs and similar things) because I wouldn't have been able to deal with that. I had the feeling we got closer. When we both left on a different skitrip he was so sweet in his messages before the departure and clearly let me know he wanted us to stay in touch. That's the feeling he always gave me: the desire to meet me in real life. We got home and he basically asked me out but he said at the same time that it couldn"t work out because he couldn't be there on time. After comparing our schedules, we saw we had both a lot of time free on Thursday and Friday . So I thought that he would ask me out again but he didn't. I started talking to him on snapchat on Sunday again and he invited me over to his house because his parents aren't there. And we had basically arranged eveything except the date and the time. When I said him to keep me updated, he didn't answer. After two days I asked him, because of practical reasons, if I could still come over to watch that movie. He opened my message on snapchat but didn't answer it. It's been a day now and I don't know what to do. I don't believe he just forgot to answer... Should I forget him? I know he's just a guy I met on Tinder, but it's been already 2 months we're talking and sending each other pics and I got attached to him. Or should I just ask him why he didn't answer and tell him if he's not interested anymore that it's okay?

Office attraction. I think he is interested and I am too. He's tried to ask me out about 3 times and I have about twice. Each time we tried to ask each other out something got in the way like we were unavailable or I said something that made him decide not to ask me... e. g. last time he was about to ask me out to this concert and just before he did I said something silly like 'jazz is not really my cup of tea'. And it made him change his mind :( :( :( (I know I know)

So I bought these tickets to this concert that I really want to go see. I think he would be interested too. I was thinking of saying to him: "hey I've bought these tickets to see _______ and my friends aren't really keen on coming with me. Would you like to go with me?"

I want to make it seem more casual which is why I put in the 'friends aren't keen on it' thing. With all that's gone on it does seem like he doesn't want to be cornered into a date or something. I'm confused... as you can see! Any thoughts appreciated :)

So I really like a guy in my major. We have most of our classes together and do group projects together. We spend most of our days with each other.
Should we date or do you think it is a bad idea?
