Bad idea to send a thank you text after first date?

Anonymous
Went on a date with this guy recently and we had a good time. At the end of the date he said rather enthusiastically that it was really nice meeting me and that he hoped to see me again.. I realized I forgot to thank him so I sent him a text 30 min after we parted ways to thank him for dinner and that it was nice meeting him.. but he did not reply my text.. so I assumed that he lost interest just because I sent him a thank you text? I usually don't send thank you texts but I forgot to thank him and I did not want to appear impolite..

it has been almost 2 weeks since then and he hasn't contacted me since.. I am thinking if I should just drop him a text to ask if he wants to hang out again?
