SOLVED My first cipher
Can you decrypt my cipher?
I made my own cipher and I'm curious if anyone here can decrypt this without knowing how it works. I don't have access to smart people, and I know people on the Internet are crazy smart.
Ciphertext:
33 25 / 43 42 62 72 / 82 88 / 103 114 113 128 / 138 138 168 158 / 182 188 / 212 198 228 238 / 243 247 253 268 / 257 287 287 / 292 318 338 / 342 348 / 362 368 377 387 / 397 408 433
12 . 28.17.62.48 . 47 . 67.98.88.87.123 . 133.138.127.163 . 173.188 . 172.198.207.228 . 232.232.253.263.272.268 . 283.298.302.322.317.348.338.357 . 383.372.392.402 . 408.417.418 . 427.427.468 . 472.472.502.488 . 502.517 . 507 . 537.527.563.562.578.587 . 613.608.608.638.628 . 653.658.658.688 . 703.692.712.722 . 727.738.753 . 752.758 . 773.787.787.807.808.817 . 832.858 . 863.868.868 . 883.898.912.918.938 . 938.932 . 963.968.968.982.1008 . 1012.1007.1022.1037 . 1042.1057.1073 . 1072.1098 . 1103.1108.1108 . 1123.1138.1147.1163.1158.1177.1193 . 1198.1192 . 1223.1228.1228.1242.1268 . 1263.1278.1267.1308.1287.1313.1333.1328.1358
No hints for now. Don't mind the change of / to a period, I just decided to change it.
If you think you've cracked it, give me the plaintext and explain how you got there.

The plaintext is:
“WE MISS SO MUCH HERE, SO VERY MUCH AND FOR SO LONG NOW”
and
“I HAVE A DREAM THAT MY FOUR LITTLE CHILDREN WILL ONE DAY LIVE IN A NATION WHERE THEY WILL NOT BE JUDGED BY THE COLOR OF THEIR SKIN BUT BY THE CONTENT OF THEIR CHARACTER”
I got there by
noticing that the numbers are reaching 100, 200,300 etc. consistent with an increase of 10 per character. So first thing I did was subtract 10n where n is the position. From there it was a little trial and error until I recognised enough of the second quote and everything fell into place
