Why do men call to talk but then forget everything I just told them?

So i responded back to my male coworker with a text and he called me up. He was driving and had been out all day. I dont like talking on the cellphone, but since I wasn't doing much either, I answered the call. The conversation was ok but I want to note that 1. I told him I was coming back to work next week
2. I told him that I chose the worst week to come back
3. He asked why and I told him that it's a predicted period week
4. He thought it was always predictable for women and we had a whole segment about why it was only predictable to an extent.
And he does bring up pregnancy again and I think i lost him there because he expressed he wanted to have kids. Then I talked about another topic I was passionate about and by the time I was done I didn't hear any reply so I hung up the phone. (He was in his house)
Kinda stung because, how long was i talking to myself? However I already knew he was going to say he fell asleep. What got me was when he texted me asking when was I coming in and if I was excited to come back 😒 We only had this conversation a few hours ago. WTH and it triggered me cuz my ex did this even in texts with the evidence right there
He forgot weeks of us being together and would ask me if I ever did something that we both tried for the 1st time together. Why call or text if you're going to forget or disregard what I say in less than a day? You're wasting my time and energy.
