Why would my boyfriend always be thinking of our future early in the relationship?

For context, we became officially in a relationship with my boyfriend for more than 1 week now, about 10 days but we've been talking for 4 months. However, aside from being clingy, and always mentioning that he's always thinking of me. He also told me he already told his mother that he has feelings for me and his mother told him to just marry me.

He also said he wants me to be the person he'll marry and he keeps asking whether i want to take care of our baby. I told him I'm afraid of getting pregnant.

Anyways, I find the future reference a bit scary because I'm actually a fearful avoidant and have commitment issues but surprisingly I grew to love the guy.

So, now, why would he be thinking of those things so early in the relationship?

He also told me I seem to be different from the others because on his previous relationships, the women all cheated or lied to him. He easily cries and seems to be the "woman" or baby in the relationship. Whereas, i think like a man lol.
