Hey cacai07,
Towns only get deleted if they haven't reached the EMA yet and even then it takes ~5 weeks. If you haven't logged on for 5 weeks, then it's possible your town was deleted.
It is also possible that you're not logging in on the right servers.
If you look at the URL of your town, does it start with en? eg: en5.forgeofempires.com/game
