My partner doesn’t want have sex with me ?

My partner keeps saying that he has mental block that he poking our daughter during sex so he hasn’t touched me in over month and I keep bringing it up as I just feel unloved no sex making this relationship so passionless and making me think he cheating I just wondered if anyone else partner saying same thing because this just all seems like bullshit this my first making it so far in pregnant 28 weeks and just feel connection going ??

Making me feel insecure and unloved
