Husband and I are done trying

I meet my husband 4 years ago we got married 3 years ago have been trying ever since. Found out a year ago i had pcos so started metaformin and other meds to help but no luck. I have a 15 year old who's a freshman. My husband is a truck driver so makes it tough to try. He told me last week he doesn't want to try anymore because he wants me to go with him when my daughter graduates at 1st i was devasted but than i went and spent the weekend with him and i realized i miss him if i have a baby it'd be 18 years or more before i could go with him long periods of time and honestly i just Wanna be with him. Here's my question how do i get over the feeling that i failed? How do i give up something I've wanted since my daughter was a baby? Any tips or advice would be really appreciated.
