To find this strange? Friend

[RedWineAndCheesePickles]

I know this is a 1st world problem, but i between all the doom and gloom we need 1st world problems now and then.

I was good friends with one of the school mums for about a year, got on well although she did take the pee and use me for money at times and then conveniently forget to pay me back, along with a few other moments.
When I reliezed what she was doing I took a step back and stopped inviting her round as it was never reciprocated. I still made a effort to say hello to her and have quick conversation when out and about.
Now she'd point blank ignoring me. I've said hello a few times for her to hurry past pretending I'm not there yet she's all over my social media liking posts, (every post) even posts I'm tagged in.
AIBU to find this strange like if you want to pretend I no longer exist why would you be all over social media like that?

Disclaimer; no I'm not a teenage girl arguing in the playground sadly I'm to old for that shit I'm just confused.

She's not worth an ounce of your thoughts. Good riddance.

she's playing games. Let her get on with it.

Block her

I've had people on my friends list on Facebook just walk passed me in real life too. They are then removed as if u can't speck to me in real life your not my friend on Facebook. People are strange it's the same as texting or comment things online that u would never say to someone's face. Just move on she's realised she's not getting any more favours from u.

I find a lot of social media behaviour odd, but yeah. This one is strange. Maybe she wants to appear to be on good terms with you to others? Either way, from the sounds of it it’s good you’re well rid of her.
