What is the ruling on a suitor forcing his fiancée to leave him after the marriage contract?

If there was consummation of the marriage or a legitimate khalwa (private seclusion of the spouses), then the divorce is revocable (raj’i), and the husband can take his wife back during her iddah (waiting period) without her consent. If the iddah ends and he has not taken her back, then he may propose to her anew. The divorced woman is entitled to her full mahr (dowry) after consummation or khalwa, unless she waives it.

The questioner's statement "I was forced to leave him" is unclear, because the bond of marriage (al-isma) is in the husband's hand after the marriage contract is concluded.
