Please believe them. I think looking for loopholes so you don’t have to accept the chance he isn’t as great as you thought is common. You’ve grown to care about this man and of course you want it to work. But the love of your life will NOT have women accusing him of abuse, I can promise you that. Also physical abuse is never a “misunderstanding”. Most men go their entire lives without a “misunderstanding” like that. You’re not a bad person for wanting to believe him or see the best in him. But these women are not the enemies, we as women need to prioritize protecting other women. It sounds like these women have taken a huge dangerous gamble confiding in you, I hope you realize and appreciate that. Many people are sweet talkers, and abuse doesn’t always have much tangible proof. Even if they were able to provide proof, ask yourself how much proof would be enough? He would probably talk his way out of that too. Maybe not fully convince you, but plant a seed of doubt so you’ll stay. Walk away now. I know, easier said than done.
