I knew a great guy whose first wife left him while he was gone in a business trip and he still supported her financially hoping she would come back. He asked me out but I didn’t like him like that - friendzoned. He remarried and after two healthy boys, his second wife had an affair with someone next door. He was so good, loving, and giving. I hope he is happy now. He just had terrible luck with partners. It was not like when he married he did it irrationally or out of desperation or loneliness. His ex-wives seemed very normal. I never picked up on red flags in his choices. You never know how your choices may turn up..
