How does a shy guy react when offended?

This shy guy clearly likes me but has problems making a move so i made it easy for him by inviting him to a dance lesson that i was taking since he already came by the other day to check it out. He didn't come in but was watching from outside ( i didn't see him). He didn't come that day i invited him but my friend told me he was downstairs at the gym the same time as the class went on upstairs. He texted me afterwards; couldnt make it. To ease his mind i texted back; lol darling ure shyness is in a whole another level but its ok. Come whenever ure ready :). He didn't open my message until 2 days after which is unlike him and he didn't text anything back. Did i offended him?

Urghh this has been taking 6 months. I dont know what to do anymore. We using different method of approach. He wants to bump in to me casually by going to places were i usually go (im too spontanious so he never sees me there) and i like to plan things so i invite him on casual things with my friends which in tge beginning either got cancelled/prosponed so it scares him even more if i attempt to ask him to join us nowadays. We hardly/ not at all see eachother anymore. Why doesn't he ask me out?
