NC and being a bit vague just as someone I know is on here and I’ve discussed this with her, hope that’s okay. Not really an AIBU but please help me give my head a wobble, I’m feeling very fragile about this.
I always wanted 4 DC and before DH and I got married we discussed this plus other fairly heavy subjects (such as finances, disciplining children, religion etc) as we wanted to be on the same page. I remember saying if 4 was too much then I’d be happy as long as we had 2.
I agreed to move away from family to a new city 3 hours away from my home town to move in with him - I was happy to do this and don’t feel any resentment about this but I think in my head I romanticised the far distant future in our own house in a lovely neighbourhood with a couple of kids. We now are between 25-30 years old (sorry bit vague) and have DD 15months who is the light of our lives. He is the absolute best dad ever, he loves her so much and is great with her. When she was about 5-6m old he sat me down and told me he didn’t think he wanted another one, I was floored, really shocked and he said he didn’t know he’d feel like this but now she was here that’s how he felt. He didn’t want to go through the newborn first few weeks in a sleep deprived fog again, he didn’t think he’d love another baby as much as her. Honestly no concrete reason just he didn’t want to. At that time I told him I needed a straight answer he can’t just say I don’t know and leave me hoping. we agreed we would discuss it again in a year when she was sleeping better and we could think about it more. We’ve sold some of her baby things (bedside crib, lots of clothes, bouncer etc) but I can’t bare to get rid of the pushchair when we no longer need it or the cot as that will make it so final. I’ve bought it up again tonight - he hates it when I bring up heavy topics in the evening but we were looking at tiny photos of DD as a newborn and I feel heartbroken I won’t get that again. We’ve had an argument and he’s basically put his foot down and said he’s made his decision.
I feel so cheated because if he had said to me straight up when we first met that he only wanted one I honestly don’t think I would have married him - we were both honest about what we wanted in the future. I wanted a big family, instead I live in that lovely house but away from family and with just the 3 of us. I love DH and DD of course but it’s lonely and I feel so sad for my sweet girl who is so sociable and friendly with other babies that she won’t have anyone around her. I understand lots of siblings don’t get on (DH doesn’t get on with his at all and I was close to mine growing up but have distanced) but we don’t have other family around either - no grandparents close (and both sets adore her) and no cousins (I’m one of 4 so she will soon have lots of them), our house is so quiet and I grew up with lots of family and lots of things happening. I can’t let go of the sadness that I’ll only have one DC, AIBU to feel this way? How do I stop it hurting?
What makes it harder for me is that I had struggles BFing in the early days so wished the time to pass faster to when she got a bit bigger and it hurt less. We also begun a house renovation when she was approx 1 month old (bad timings thanks to Covid!) and a lot of that time was spent feeling stressed. I didn’t get the chance to appreciate it whilst it was here. I also had a early MC at 6 weeks the year before we had her, i would have been due in September and now I keep thinking about it. I know some people have no DC who really want them and I fully understand that and hope I don’t come across as ungrateful because my DD is my world. I just wish I knew how not to feel so upset about it and how I can accept her being an only child. I know I can’t force him and I don’t want to anyway as he will never have that same bond with another child but will I always quietly resent him for this decision? Has anyone else been in a similar position and knows what I can do to accept this? It makes my heart hurt 
Sorry this post is all over the place and sorry for the humongous essay
I’m just a snivelling mess currently and need AIBU to put me straight.
