Emptynest, I'll do my best to articulate how I knew, finally that it was over, but it's hard to put into words.
I think I had a 'lightbulb' moment. I suddenly saw our marriage in sharp focus, what it had become, not what I wanted it to be.
Twenty years of marriage, three lovely teenagers. Both of us working very hard, I'd returned to teaching after a long break to bring the kids up, but we both agreed that I should return, the money etc would be good, his career had gone a bit static. I would still have the long holidays. Things changed though. Whilst he wanted me working, he wanted me to still do everything at home. So after being used to me doing 24/7 home stuff, he had to pull his weight. This caused resentment. He started coming home later and later, he became detached. I bent over backwards trying to please him. But he detached, became cold, distant. The kids were older, doing there own thing. Typical teenage angst over boyfriends, he didn't want to know. Homework, exam stress, he just avoided it all. He just did his own thing. Didn't want anything to do with family get togethers, didn't want days out, nothing. We were no longer a family. It was me and the kids in one corner, him in the other.
Two years pre-break up, I strongly suspected an OW which he repeatedly denied. I couldn't find proof but I knew. I blamed myself, tried harder and harder. I lost weight, looked awful, GP put me on ADs for anxiety. Still I kept trying to fix it.
He eventually told me that he was unhappy, and didn't love me any more. Still denied another woman. Was mortified that I could even think it. So we decided to make it work. But he did nothing, I tried everything.
Then he said it wasn't working and we should split when our twins had finished their A levels. I was gutted, still thought we could make it work.
From his announcement, he started his life as a single man, but still in the family home. It was the worst time of my life.
The lightbulb moment happened when he returned home, after two nights staying out, which he hadn't told me about.
He walked in, and sat down, like nothing had happened switched whatever the kids were watching on tv over to Sky to watch the football, and asked me what was for dinner, because he was starving.
I went bloody mad. I saw it all in a split second, the total mug I'd been. I turned the tv off, asked the kids to go upstairs, and told him it was over and to get out. He laughed, so I went upstairs and packed his bags. He went. I was fuelled by anger like I've never known.
I filed for divorce a week later.
Yes, of course there was an OW. He had been with her for over two years. Someone he worked with, his PA in fact. I'd actually bought her Xmas present from him, because he was too busy, one year, and he'd always bought his team a present. Bet they had a right chuckle about that.
I thank God for the lightbulb moment when I knew and found the anger and strength. I got me and my life back, and it's so much better than I ever thought possible.
