IVF and marriage

Hello all, how have IVF and the infertility journey affected your relationship? After almost 3 years of IUI and IVF, non successful, I fell my marriage has reached a rather insecure point. We a re disconnected. I admit I am frustrated and really hard to please. I am a fighter and I was the one who kept pushing for a second IVF. Now after another failed transfer I keep planning my next transfer while my husband wants to plan a holiday. He says I need a break and I need to do things I love other than seeing drs and taking meds. We have already wasted so much time not because we planned to but because a child was not ment to be in all this time. We are both broken hearted and it seems to me he's giving up. I want a child and I'd do almost anything to have one but I don't want to lose my marriage. How do you keep your relationship sane and safe when love doesn't seem to conquer it all?
