Should I leave and IVF alone?

[haventmadesourdoughbread]

Sorry for the long post
I’m 43, I didn’t meet my husband till my mid/late 30s, I was happy but apparently my husband never has been. He blames me and our marriage when anything negative happens to him. We’ve had counselling but he’s still miserable and lockdown has made it worse. He keeps saying he wants to leave but he won’t (his parents split up badly and it affected the children so I think he scared to be the one to do it)
We have a 4 year old girl conceived via IVF (mainly because he hardly ever wants sex with me and seemed to deliberately avoid my fertile times). He wanted a child more than me but my “condition” was 2 children as I am an only child who had old parents who have both died and I didn’t want my child to have to go through that alone. I was very very clear on that and was clear I would rather have no children than just one. We’ve had one round of IVF for number 2 had agreed 3) but he has now said he’s so unhappy with “us” he wants to stop IVF. I think basically he’s forcing me to make the decision to leave
So my question is do I give up a sibling for DD and stay with a man who actively says he doesn’t like me and has been miserable for years or do I leave and if I leave do I try IVF alone even though due to my age there is a high chance it won’t work? I can't wait to find someone else due to age
Has anyone here had IVF alone at an older age and with no support network? Im worried I’m
being selfish wanting another child and that I’m giving up financial security for unknown but I will resent him if I stay and give up my chance for child 2 and he leaves later anyway. TIA

OP I’m 42 and just starting the journey to IVF on my own. It’s probably the scariest thing I’ve ever done, but I’d rather have a child and still have the potential to meet someone nice later, than keep waiting for someone nice and miss out on having a child because I’ve aged out.
It is not your responsibility to make him happy, that’s up to him. Do whatever is going to be best for you and your daughter.

@Corruptedtongue In a way I wish I could get to that with my husband but I can't see it, he's just very unhappy and I try but the more I try the more unhappy he gets.
@Sunbird24 thanks! its reassuring to hear I'm not the only one considering going it alone at 42. Good luck with it I hope it works quickly

From my two successful IVF pregnancies, I was physically fit just before treatment. In my unsuccessful attempts - I wasn’t. Think there are some studies that relate this to hormone levels.

Am interested in the outcome of your journey. Am nearly 43 and desperate for a 3rd child since having a miscarriage 10 months ago. My husband won't hear of it and it's tearing me up inside am considering leaving and having IVF alone but it's a big decision. My marriage is variable sometimes we are ok and other times we just can't agree on anything.

I feel like there's a little clock ticking away inside me. How did you get on with your IVF did you do it?
