The removal of conditions phase is about the past, not the future: whether the marriage was real at its inception, not whether it is viable going forward. Many marriages don't work out, for a variety of reasons. The immgiration issues may--or may not--come into play.
You should be aware that the affidavit of support you signed when you initially sponsored your spouse survives a divorce and may carry some financial obligations, but you are not obligated to participate in his petition to remove conditions. That petition can be filed with you (so long as you are still married) or without (either before or after a divorce).
If his continuing to contact you is not OK, you can explore a restraining order, but if you are not concerned about safety issues, perhaps you could get some input from your divorce attorney?

Affidavits of Support are contracts with the US government wherein the person who signed them agrees to reimbures the Federal government for the costs of certain means tested benefits, if the immigrant requires and is given those benefits. The US government can sue to obtain that reimbursement.
Affidavits of Support cannot be withdrawn once accepted by the government. They remain in effect until one of the following events take place:
1. The person for whom it was filed has legally worked for 40 quarters in the US.
2. The person for whom it was filed becomes a US citizen.
3. The person for whom it was filed permanently leaves the US.
4. The person for whom it was filed dies.
5. The person who submitted the Affidavit of Support dies.

A restraining order will not directly affect your husband's ability to remove the condition on his two-year permanent residence card; however, a divorce will. If you are divorced by the time your husband needs to apply to remove the condition, then your husband will have to file for a waiver of the requirement to file a joint petition. In order to get a waiver, he must show that the original marriage was entered into in good faith (but later fell apart) or extreme hardship to himself, if he were to be removed. There are some related grounds for a waiver as well. If the husband obtains the waiver, then you will still be responsible to the government under your support contract. Happily, it would be a rare case in which your husband actually received any reimbursable benefits and even if he did, these contracts are rarely enforced. Your safety should be your concern in seeking a restraining order. You no longer control whether or not the husband keeps his permanent resident card.
