The back story:
Split from H last year, but we are still in the same house.
Both trying to save so we can move on to different dwellings.
Separate bedrooms, don't really interact anymore, move like ships passing in the night, remaining polite and civil for sake of 8 year old daughter.
He's been dating, and seems to go straight from 1 woman to another if the 1st one doesn't pay him enough attention. They never come in our house, always dating away and hotel rooms etc.
The situation now:
Latest GF, approx. 3½ weeks in, love bombing each other like crazy, always texting / talking and meeting up almost every evening.
They went away for the weekend and she sent a gift for our DD. DD doesn't even know she exists and ExH wants to tell her about the new GF already. I put my foot down and said absolutely not and you have to say the gift is from you.
AIBU to be livid about this gift and how fast he's moving? or is this normal these days and I'm just old fashioned in my views? (Me and Ex are both in our 40's, new GF is in her 30's)
