Ex's girlfriend at my house acting odd

[TheSilentSister]

So, for context, I still live in the marital home and ex divides his time between another country (where his g/f lives) and here. He's currently here and his g/f has come over (agreed by me). She's acting all weird. We've met and she's stayed here before. I'm wondering whether it's because I've lost weight and actually look younger than her now or if there's other reasons. It's so odd. They've been together for 6 yrs and the last time she was here I was quite a bit overweight.
I won't say I'm bending over backwards but I'm being incredibly civil given the circumstances. Ex is running around like a headless chicken.

More Context is needed

I don’t get why people are being nasty to the OP due to a name change fail. She’s right that if you change from the app to the site opened via web browser, whatever other name you’ve been using previously will be the default name. People change name all the time according to what they’re posting.

The house may not have been sold as it’s been agreed that the DC live in the family home until they’re adults and the OP says her ex lives abroad half the time so not worth the expense of another property if they have space to live apart in the same house and can’t afford two separate properties.

A bit sick to bring his gf to stay in the house though and as OP says she hates it and he’s abusive, why is she getting castigated?

If I was the gf no way would I be staying there in his wife’s home!

Gf may well be feeling a bit insecure now you’re looking better OP. Not your issue and she must know she’s with an arsehole of a man to even bring her there (and she’s a bit of an odd one to agree to it) so her stew in it. I’d find it hilarious.

Sounds like you are both his partners.
Your self-esteem is on the floor or you'd not give a shit about what she may think about your looks. As if she's your rival. Then again her self-esteem must be shot to pieces too, she really should walk away and leave the 2 of you to it.

Obviously it all stems from you being tooooooo sexy.

@tescocreditcard ehhh

Op, name changed and actually tried replying to her own thread asking if kids were involved 🤣🤣 therefore a name change fail.

Are you divorced, is there a settlement? The odd thing is your ‘arrangement’.

OP is SilentSister and Walkingalot. Tescocreditcard asked about kids.

Nobodies asked about the ex yet.

Why is he running about like a headless chicken??

I am Walkingalot on my mobile phone it seems and SilentSister on my PC. No big deal.
I haven't got a b/f anymore. That was irrelevant historic info.
House is up for sale and divorce finally going through.
I've previously got on very well with ex's g/f and genuinely thought that maybe because I was overweight and she was slim and younger - she saw me as no 'threat'. I don't know.

Yes it's all a bit (very) weird and I am sick of it and close to breaking point.

He's also exploiting his girlfriend's good nature and that's why she's acting weird. She hates it too. You both need to tell him to fuck off.

Is the "weirdness" aimed at you or at your ex or is she just generally acting odd? That would give us a clue. I doubt very much she is acting weird just because you have lost some weight OP
