If you want religious advice:
The Catholic Church does not care if a civil annulment or a civil divorce is obtained; neither is recognized as having the authority to undo a marriage. Either way, your wife will have to go through exactly the same process to obtain a Catholic annulment.
If your wife is Catholic and you weren't married in the Catholic Church, then she has trivial grounds for Catholic annulment.
Your situation does not constitute fraud (canon 1098) or error (canon 1097 §2) in terms of getting a Catholic annulment. Most Catholic annulments are granted for "grave lack of due discretion" (canon 1095 §2), and that is probably what will happen in your case as well. Your wife's attitude would also qualify for a Catholic annulment for "positive exclusion of the good of children" (canon 1101 §2). However, if a Catholic annulment were to be granted on the latter grounds, then it is likely that your wife would also receive a "monitum" or a "vetitum" which would restrict her getting remarried until she changes her attitude about children.
