In fairness, your fiancé does appear to be adopting a mature and responsible approach to your relationship. He doesn't want to throw away what you have and is prepared to take steps to make it work.
Equally, you want to take some time out to think things through.
Your situation is more suited to a modified form of no-contact. If you want, you can attend the counseling sessions while maintaining no-contact outside of these times. However, your counselor may advise differently. If you feel strongly about waiting for 30 days, then you should let your fiancé know this, and ask him to make an appointment after this time.
