Firstly I wanted to thank you all for the responses, I didn't expect so many, was hoping to have one or two!
I am glad to hear the majority (everyone) thinks IABU, this is what I needed to read, as I woke up feeling very low and it's helped boost me up.
I know my anxieties are unreasonable, and it's a silly thing to seem to get upset over, I can't help it, I am seeking support for my anxieties- I am on medication for it, my problem is obsessive questioning, I can over analyse anything and my head feels like it bursts with a million questions, not something I am proud of or like living with, but unfortunately that's the way it is for me.
I guess my main problem with last night was it brought me back to the first time we had this argument (yes we had it before) and it was very heated, went onto to other things and resulted on him walking out on me 4 months pregnant with my second DD.
Anyway fast forward, he obviously came back, a few days later but I hate reliving that moment, as it caused a lot of stress for me and my relationship and my DD came at 27 weeks, will never know if it was the stress but I still blame myself now, anyway- that's irrelevant.
It wasn't only that part that made me cry, someone wrote that it was silly to get upset over that, it was the whole thing mainly, also when we were speaking about my father he said something along the lines of- (sarcastically)
Ok, Let's have a one hour conversation with your kids about their memories with your dad! - (he's never met them, he passed before my first was born)
This upset me and led me to say-
That's a nasty thing to say, that's like me saying let's have a one hour conversation with the kids about your Gran.
This led onto him calling me a spiteful c-nt.
I know it was a nasty thing for me to say back, but I was trying to show him how insensitive that was seeing as he knows they have no memories with my dad!
I guess it all boils down to me and my anxieties and the insecurities I have with him because there have been many occasions where he's said horrible things or done horrible things that make me feel anxious and insecure when I relive stuff that's happening in the past.
Having said that, he is a lovely DH and I married him for good reasons, and he has changed and hasn't as such hurt me like he has in the past, touch wood. But I can't shake my anxieties off, and I know I am being unreasonable as I know my head sometimes doesn't think like a "normal" person and hence why I wanted to hear it from others, so I can learn and understand that DH wasn't being unreasonable.
Also, the religious comment- I am a Sunday School teacher so can say I am religious
although I didn't mention it in my OP because I didn't think religion was relevant as there are spiritual people who don't have a religion.
Yes the post was about that he meant after HE dies there's nothing, so he can't love us after death.
Thank you all, a couple of the posts even made me giggle. Like "I told you so" and "she was bloody right"
