We started TTC 4 years ago. After a couple of years and various tests we found out we couldn't naturally and our only hope was IVF. Since then we have been on an extremely long waiting list for treatment. Finally, we got the news last week that our names are now at the top and we should be beginning treatment soon. 
It has been a very difficult time and I have really struggled being around pregnant friends and babies/young children, and have drifted apart from some friends as a result. Obviously I'm happy for them but I just find it really upsetting. I'm not quite as raw as I was a couple of years ago but I still find it really hard.
We have been invited to a friend's birthday gathering the weekend after next. It's a daytime affair so that everybody can bring their kids. There will be at least 2 heavily pregnant women there, plus around 15 children ranging from newborn to 5 years old. Plus it seems like every time I go to something like this, another pregnancy is announced.
So I told DP that I didn't think I would feel up to going. He doesn't see what the problem is. He doesn't understand why I'm still upset by these things and thinks that now we're at the top of the waiting list, I should be over it. And if I'm not over it by now, when will I be? (Er, when I'm holding my baby in my arms perhaps?)
Tbh I was so
that I just burst into tears and told him to f*ck off. I have pointed out that there's only a 1 in 4 chance of the IVF actually working and more likely than not we still have a long road ahead of us. He thinks that I am being overly negative and that the hardest part is over 
He has been fairly supportive prior to this but I don't think he's ever really understood how heartbreaking this has been for me (he's quite laid back and although he wants kids he's never been desperate for a baby to the point where that's all he can think about).
So, is he right? Should I suck it up and force myself to go? Or is he being an insensitive knob?
