TTC got me like 😞

So we’re on month 7 of TTC and it’s broken us, we’re constantly arguing and not getting on and it’s made me so stressed I was in tears the other night and I feel like he just doesn’t get it because he’s so relaxed about the whole process whereas I feel like a massive failure every month af shows, and being in my 30s I feel like time is against us. I feel like if we can’t even handle the stress of ttc how would we cope with a baby if it ever happened and maybe we’re not cut out to raise children together. From most of the posts on here it looks like it brings couples closer together but has anyone had the experience of it pushing them apart and what did u do to fix it?
