1. You are doing it wrong.
2. You should get better patches and glue.
3. No, patches can last indefinitely.
Let the glue dry! Err on the side of too long. I once forgot I was in the middle of patching (at home), and hours later, I applied the patch. It worked great. You shouldn't need more than five minutes, but if you're in doubt, wait longer.
Rema patches are the best, though I am usually successful with other brands, including no-names.
Rema vulcanizing fluid is MUCH better than the others because it makes a chemical bond that makes the patch and tube intertwine at a microscopic level. Other glues are just sticky.
When the patch is dry, the edges should not show any gaps. At that point, it is tempting to add glue to finish the job. This is guaranteed not to work. Peel the patch, clean the tube, and start again with a new patch.
You can do this. I've taught dozens of kids to do it.
