I never got a notification of your comment - so apologies for the delay!
Yes, I've experienced this as well. In fact my last relationship ended under similar circumstances. I went out for a walk with my daughter, which he was upset about because supposedly there was something he needed to talk to me about - but he was constantly interfering in my relationships with my kids - and that day I suddenly reached my breaking point. I had no intention of ending our marriage. We had recently bought a house together. I imagined we'd grow old together. But something in me snapped and I took my dog and left and never went back. I'm still sad about it and I know he is too, but I just couldn't do it anymore. I don't know why it's like that.
