Conflict surrounding having another child

I’m experiencing issues with my partner in regards to having another child. I’ve always desired to have another baby after my first daughter because now she’s a bit older and I’m ready to give her a sibling hopefully. However my partner and I aren’t seeing eye to eye about that.

Initially we began trying and it’s been 5 months but for a few of those months he wasn’t fully giving it his all. Hopefully I’m not being explicitly but during intercourse he wouldn’t fully ejaculate and just pull out and tell me he did when I doubt he did. Perhaps he did some of the way but the last month he finally did finish inside and I still didn’t end up pregnant.

So I’m trying to get him to understand that even with full ejaculation conception is not even guaranteed. So sorta half assing it is definitely gonna make things harder. Then today I was upset still since the other night he yet again didn’t finish inside me and that makes me really hurt and sad because I’ve been wanting another child and it feels like it’s not gonna happen.

So his reasoning is that I’m not ready and I’m not emotionally mature. Because I’m crying and getting upset over him deciding to withhold himself and deciding he wants to wait to have another child. It’s difficult to be understanding and accepting of his decision. I’m impatient and I don’t know if I can wait any longer than the normal waiting during trying to have a baby because clearly that’s taking awhile so it’s like double waiting now.

I just don’t know what to do or how to feel. Then he leaves this morning and goes to breakfast without me. He says it’s because I won’t stop crying and being sad. But initially he lied and says he’s getting his taillight fixed. So idk what to do I just want to be with someone who is kissy as ready to have another child as I am. That they don’t get cold feet or back out just because they feel like I’m not ready. Just because sometimes I’m emotional like over how I sometimes feel like I have no friends and no family.

I have a small family, it’s just my mom, and me. My dad is there but he works a lot and doesn’t visit much. My grandmother died when i was young and I never knew my fathers family. So I do get sad when I feel lonely and I get depressed over my difficulty making friends. ;( so he feels like i shouldn’t be so sad about that…
