I've name changed for this.
If you and your DP disagreed on whether to do more fertility treatment, how did you resolve this? If one of you didn't want to give up and the other was happier to just move on without children? I feel bereft right now that I won't have a family. DP doesn't feel the same. I'm not sure if I can resolve this in my head. I can't force him to go through more treatment and frankly we could hardly afford it... I feel like I may become resentful (I'm partly the way there to be honest).
I just don't even know how to start thinking about this rationally and sensibly.
Going it alone is not an option for me before it is suggested.
