I have 2 DS, DS1 is 26 and DS2 25. In the last year they have both entered into new relationships. DS1's GF is delightful, she is chatty, kind, intelligent, very funny and she and DS seem like a perfect fit. DS2's GF on the other hand is very brash, rude and seems to be causing endless issues.
We have a family tradition of a weekend holiday every May, all the cousins, both sides of the family, it is lovely. We extended the invite to both GFs, DS1 GF replied thanking us for the invite but telling us she won't be able to make it as she is attending a sporting event with her own family that weekend, DS1 is still joining us. DS2 has informed us neither he or his GF will be joining us, when I asked why he said she doesn't want to and he doesn't want to cause an argument going away without her! This happened at Christmas too, DS2 told us last minute he wouldn't be joining us as she had gone in a huff about spending Christmas separately. Then they cancelled on us for New Years too (they had originally both been coming) as she decided she wanted a quiet night in and wanted him to stay with her. DS2 admitted after that he was quite upset about missing it but didn't want the argument.
Our boys birthdays are a week apart, so last month we took all of them out for dinner, at a lovely restaurant. DS1's GF was lovely, so chatty, polite, insisted on paying for the after dinner cocktails for everyone. DS2's girlfriend kept going on her phone and whispering to DS through the meal! DS2 then told us after that she didn't want to meet up with DS1 and his GF much as she finds DS1's GF intimidating. I don't really understand how this can be the case, yes she intelligent and absolutely gorgeous but she is one of the loveliest and funniest people I've ever met.
A week or so ago I met up with just the boys and DS1 said he could imagine his current GF being the "one", he spoke about how much they have in common, how supportive she is of his goals and how much he wants her to succeed too. They are so well matched, it makes sense. They are great together but also both very supportive of the other having a life of their own. DS2 then said he felt the same about his GF, as in he also feels she could be the "one". I was just pleasant about it but honestly the thought of her being a permanent part of our family fills me with dread, I imagine we would hardly see DS2 as she doesn't seem keen to share him and he is quite the people pleaser.
AIBU to be struggling with her? Should I mention my concerns to DS2 or should I just be quiet and hope it runs its course?
