In short... my sisters husband to be is a cheat. Whilst planning their wedding he’s been having an affair. It’s transpired this is not the 1st time but 3rd in their 14 years together. There seems to be drama after drama in the family with her falling out with most as she’s clearly angry and hurt and upset but aiming her emotions at the wrong people. She’s totally blinded. I’m pretty much the only one left going to the wedding from the family going and probably the only one who knows what he’s like. They have grown up children who are not going.
Dilemma, how do I get thorough the day not showing the hypercritical person I’ll be as can’t stand infidelity and am so angry at him. I love my sister so so much and want to support her, this is her dream but it’s just madness marrying him still, so soon anyway with no time to repair their relationship.
She’s started on me this week implying I’m not welcome if I do not support them both. I’m so angry being put in this position. I’ve done nothing but be there for them all always.
Any advice appreciated - thanks in advance
