Any advice to help heal

I just need to vent and maybe get some advice. My husband and I had a rough year for our relationship, I’d rather not go into too much detail but divorce has been brought up and discussed a total of 5 times since April. We’re on calmer waters now and are actively working towards bettering ourselves and our relationship but we know these things take time as well as patience to see changes from our efforts. We were supposed to be trying for a baby soon, obviously we’re putting that off until we’re in a better place but honestly neither of us know if another baby will be in our future because while we see us not leaving each other we still don’t know what the future holds. I’m hoping to get some advice on how to come back from a almost broken relationship and how to help not only myself but my husband heal. Also if anyone can give some advice on how to come to terms with not adding another child to your family in the time frame you planned or at all, I know it’s not the right time but I can’t help but grieve and have a little of resentment form because for awhile it was in the plan to try for another one before our son turned 4, now it won’t be till he’s 5 or 6. Thank you in advance ❤️
