What are your thoughts on co sleeping?

I’m pregnant and a FTM. I really want to avoid co sleeping only because I’ve seen it affect couples in their relationship and I have also read it’s unsafe for baby. I just think baby should have their own bed and parents should have their own bed. I don’t want to then in the future be with my 5 yr old still in bed with us. 🤷🏻‍♀️ I know it’s sounds so bad to say, but I’ve honestly seen it affect other couples. I feel like I sound like a “bad mom” for saying this 😆 my plan is as soon as I give birth train her to sleep in her bassinet then transfer her to her crib.
