I talked to your sister once in the Lounge, she's very sweet.
I watched my oldest sister get married three times, the first time I was in Kindergarten she was 18 and they got married at a JP. He was awesome, he was a part of our family for many years and still is. When they divorced she went banana's and married a raging alcoholic. I didn't want to go to the wedding, it was in her back yard. I wasn't in the wedding, I probably would have said no. Anyhow it was horrible and I didn't pay much attention. They divorced a few years later. She's been married to husband 3 for 16 years. He was an alcoholic for 10 of those. I didn't want her to marry him either. He's been sober for 6 years, so that's good, but I knew it was going to be a train wreck at first.
She told me that always wants to fix people. I said you can't, she knows that now. I love her and I like her Husband, although he and I didn't always get a long. But we are fine now. I'm glad he's sober and their life is normal now. Not always peaceful but fairly normal.
If they get divorced and she marry's again, I'm going to pretend it didn't happen. So I feel you on the Sister thing.
