I've never heard or read anything about marriage similar to what you quote (i.e. that marriages contracted on earth remain in place in heaven). I've looked through the Longer Catechism of Philaret, Elder Cleopas' Truth of Our Faith (Vol. 2), and Protopresbyter Michael Pomazanski's Orthodox Dogmatic Theology (3rd ed.) and haven't encountered such a teaching. You can read the Service of Marriage online here - I don't think you will find any suggestion of what you are saying.
Within the Eastern Orthodox Church a marriage can be dissolved "chiefly when it has been defiled by adultery, or when it has been destroyed by conditions of life (for example, long absence of one spouse, without word."1. Generally only a second marriage is permitted, although a third may be "tolerated only as a lesser evil to avoid a greater evil", as taught by St. Basil the Great2 (also a Doctor of the Roman Catholic Church):
We look on third marriages as disgraceful to the Church, but do not absolutely condemn them, as being better than a vague fornication.3
