Awe. That would be tough to do, even just saying it. Maybe you could try and negotiate... Let him know that you're
really not pleased about having to put TTC on hold until
he feels like its good. Relationships are work, and it shouldn't be one person over the other. I would tell my DF ((if he & I were in that situation)) that since I didn't want to pause it and he wanted to WTT for a year that we would be back to TTC after 6 mos. It's the middle ground, and that way some of what both people want is included. IMHO I think that you were right to tell him that, regardless of the amount you love him, if he didn't want what you NEED... then things wouldn't work.
I have never made any point of hiding how I felt about family and starting mine. When DF & I got together he was 18 & I was 19 and I told him that I always wanted to start my family young and I planned on it. About a year later we started TTC and he comes with me to all of my Dr appointments since it's been almost 15 mos and still no luck... just crazy cycles. He is even going to get a semen analysis done when I get blood work done.
If your SO loves you as much as you love him, he should go that little extra step for you like you would for him.
It seems like he does want LOs, but in your situation you can't really risk WTT.
