TxNVSue2023: The matter was resolved when we married.
Did the elders on your judicial committee feel the same way? I think that most JWs would take the approach that having sex prior to marriage is a sin, and they would not make an allowance for how close you were to your wedding day. But the verdict is really down to how they view the issue as a whole.
If you convinced them that you were repentant, they are likely to be open to an early reinstatement. But as Blues Brother said, there are no hard and fast rules that cover every possible situation, and the elders are making a judgment call. If you really want to stay in, your only recourse is to accept whatever they decide and see what kind of schedule they have in mind.
As some of the others have said, it's not a course I recommend, but there is a clear path for you to return if that is what you want to do.
