This is too important to leave to opinions.
Please consult someone within the marriage tribunal at your diocese for an accurate answer.
Everything I have been taught and have read as a marriage prep instructor has said that you must wait to receive Holy Communion until your marriage is blessed, regardless if you’ve been to confession.
The reason being for that is that as a Catholic, you chose to marry outside of the Church and must reconcile that issue first. THEN go to confession and receive Communion. You’re already half-way there in seeking and receiving the annulment. I have a sister-in-law in the exact same situation, and she has been instructed by our diocese (Phoenix) to continue to abstain from Holy Communion until her marriage is blessed. (Her husband is also balking, as well - we’re praying and giving him the time he needs.)
Perhaps when your husband sees how much this means to you, his heart will soften. Remember, you’re not forcing him to convert, just asking for his cooperation to help make your spiritual life complete.
In the meantime, live your life as a faithful Catholic knowing that Jesus is thrilled to have you back! Let Him motive your hubby!
