why do you think he unfriended me?

I'm female in my mid 20's and I'm a gamer, I like to play multiplayer games with people online-

I got into a game with 4 randoms and we were having so much fun, until the game disconnected. I really didn't want to end that game so soon, so I tried adding the players but unfortunately there was only one that was on the same platform as me.

I added that one, and we chatted and shortly after we joined a game together just us. He's male and I'm unaware of his age I just know he has a roommate- so possibly over 18.

Anyways, we played that day and then the next day we didn't talk at all, which was no issue. he hit me up the next day after that and asked me to play, I told him I was busy.

We didn't talk for about 3 more days, and then he asked me if I stream my games, and I said no I don't and that was it for that day

About a week goes by, and he's asking to join my current game I was in, but I told him i was playing with my child on two player. He understood that but that was also the last time he said anything to me.

After about a week he unfriended me. I actually seen this right away as I was just refreshing my screen at the time, like he literally did it right at the perfect time for me I was able to see he unfriended me and I just unfriended right back.

Now I'm wondering like why though, is it because I have a child? or because I kept telling him no? I don't understand. Me personally I have so many gamer friends, we know we can't play every single day together and we're always on different games so we don't bug eachother, it seems like he wants a small friends list to stay loyal too or something.
