Choosing to be childfree after infertility - will I regret it?

For the past 5 years my husband(34M) and I (32F) have been trying to have kids. We have recently decided to not pursue any further treatments because we are just done, emotionally and physically. We are tired. In couples counselling we both admitted to each other that we were done.

Part of me is scared that we will come to regret it. Part of me would be relieved to move on to something else. I have no older child free role models in my life, so I find it difficult to picture.

Women over 30, what's your life like if you're childfree/childfree after infertility?
