Ok. My partner divorced his ex over 30 years ago. (She had an affair) all remains civil. They have 3 kids. We’ve been together 10 years. His niece (his sister daughter) getting married this year. His ex wife been invited, I feel huffy about this ( of course his adult kids and their partners and kids invited, so ill
be expected to sit with them all. He’s older (considerably) than me as is she. I just feel crap and will be the “add on “
AITA for thinking she shouldn’t have been invited. They’re my family and in laws now, not hers. ?
