My SS, late 20s, has a GF in her early 30s. SS was estranged/alienated from my DH, they have been getting reconnected for a year, and it's slow, but going quite well all things considered. However, I don't know if this GF hates DH (and me by proxy) given what she would have been told 4 years ago from a very negative POV... or is socially phobic or highly anxious... but this year over may 5-6 get togethers, she makes virtually no eye contact, gives one word answers to all questions, and her overall vibe is the most unfriendly I have ever experienced. SS chats away, and we try to make the best of it, but it is so very awkward. Then last night she was snippy when I was speaking from an assumption that they had moved in together (based on seeing "their" place, the room she would do her crafts in, the stuff "we" bought, how excited she was about the bath tub, how they'd looked for a place to move in together for years, etc etc last fall), and she said "I have never lived with SS, and I have mentioned this several times" in a snippy tone. I apologized, got no reply and spent the rest of the time in WTAF mode... DH later confirmed that we had every indication they lived together. Now maybe they are in conflict, had just had a fight, who knows, but honestly, with 3 kids of my own, I have met many boyfriends and girlfriends and chums in this age group, and her frosty detached bordering on hostile demeanour is baffling. I want to support my DH, but I hope they just hang out sometimes and I have to deal with this GF on occasion as it is so very painful. Maybe eventually DH can ask SS if there is anything to do to make her more comfortable. When she was in the washroom, I whispered to SS that I was clearly mixed up and had offended GF, and he said thanks, she just spends a lot of time at his place, and she is just tired. Hmmmmm to be that rude and unfriendly in your early 30s because you are "tired"???? Open to advice and commiseration.
