Co parenting n sex

Hv u ever co parent n got to where u didn’t even acknowledge them? My son dad n I got into it 3 weeks ago...Because I went to work early for overtime? Keep in mind he is off on the weekends, stay n the same house. On an everyday basis he is on the game our 3 yr old is playing n eating while he is in the game room. He will hv you kids on so our son is chilling basically. I was so pissed because 1) we got into a full fledged argument in front of our son 2) too busy on the game playing.3) undermining my job as a Mother- he says I don’t watch him. We work separate shifts he works 7-4 weekdays n I work 1215-915. little guy is at daycare from 8-5. When I make it home my son is up waiting on me, so we can talk n play for about an hour. I don’t go out,hang out ,drink or smoke. I go to work n home. As far as I’m concerned the daycare watch him n take great care of him while I’m at work. But once he realizes I’m not talking to him he turns around n ask me for some Ass!!!! Really dude, thinking to myself I would be a dam fool to hv sex with him. And no I dont hv sex with him at all since b4 I had my son. It literally may hv bn 3 times n 3yrs. We don’t sleep n the same room since i found out I was pregnant with my son.I am attracted to a person personality n how they carry themselves. But I guess he thought I was gone give in. So he ask again lastnight. Y???? We hv iPhones so I let u see I read ur message n still don’t respond. Keep n mind I’m still not speaking to him. I take dam gr8 care of my son. He really boiled my skin. I know my worth u will not disrespect me n think I’m gone hv sex with him. Even if u did respect I’m still not gone hv sex with him. what u think about this situation
