Support for husband going into 3rd IVF cycle

My husband and I are preparing for our 3rd IVF cycle. Our 1st cycle resulted in 1 embryo that failed transfer and our 2nd cycle didn’t yield any mature embryos for transfer. We took June off, met with new doctors for 2nd opinions, and did our 3rd IUI in July (results come in on Thursday). If this IUI cycle doesn’t work we’ll do our 3rd IVF cycle in September. This has been a lot and my husband is feeling the stress and he’s mainly concerned about me and how I would take another failed cycle. We’ll be consulting our therapist for preparation, but I want to understand what others have done to help their partner feel supported. Any groups or podcasts or books? I appreciate the advice and support. I am so grateful for this community.
