Why didn't this girl accept my friend request on fb?

She just want to get fuсked in a group sex, therefore she accepted a number of people. Then, the group was full and you can't fit in.

Because she doesn't want to. Accept and move on. I have had young men in their 20's sent me (I'm 60+) a friend request. What would a woman of almost 70 have in common with a 20 year old young man.

Hmm.

Maybe she was hit by a bus.

Maybe FB had a system glitch.

Maybe you shouldn't read too much into this. If she's like that, do you really want her as a friend?

Maybe she's been having a busy weekend, and not so much on FB, don't stress give her a few more days, or t could be that she's seen that you're interested maybe when you've talked to each other, and thinks that by accepting your friend request she'd be opening a new door, not necessarily of friendship, but a door that can lead to more serious stuff for you
