Feeling lost... wanting another baby but husband doesn't get intimate...

I don't even know where to begin. Tonight I'm completely broken and lost. My LO will be 3 next month. I always envisioned having another one by now, I'm 34, I'm ready. I'm a great mother, I do the best I can to provide my LO everything, my husband says this all the time. I've expressed to him I really want another baby but he doesn't get intimate with me. I am the same weight as I was before having a baby, maintained myself. On the contrary he has completely let himself go. Surely it should be me not wanting sex but he says because we fought alot in the past year ( terrible twos got thr best of us) he doesn't want intimacy. He then uses the weight excuse yet fails to go to the gym, then work excuse. Then he says the bed is uncomfortable so we got a new one. I express to him when he's the right moment to conceive and he says it adds pressure when I'm the one who has been waiting 2 years for this to happen without the pressure. His sexdrive doesn't match mine, I'm high and he's low to none. It bothered me at the start but I got used to it, however now it's none and I want another baby. We have talked. Argued. Hugged over it. He says he loves me, I'm his world. Yet nothing. Today I'm ovulating. I'm ready. Yet a very old friend of his wanted to come over for dinner and it turned into a late one. He's still with him catching up and I'm upstairs crying. Every month there's a new excuse. I can't bare it. He's a lovely loyal sweet man. I just feel completely disconnected sexually and feel frustrated that he's wasting my fertile time. I feel angry that others find me attractive and want me Yet my own husband doesn't even when I look the same as when we first got back together. I have noone to talk to this about. I feel shame speaking to my friends about this, I don't have a sister. I can't talk to my mum about this because she would be so worried even though she's the one person I can trust with anything. I feel so lonely and lost. He is my best friend but I also am starting to hate him. And I don't want to go down that path because he is my husband, the father of my child. And an amazing one. But I feel so frustrated with his behaviour and further talking about this just makes things more awkward and difficult as we've already had so many discussions around it. Please can I have some advice.
