1. You did nothing wrong, you don’t have to inform him when you contact friends, no matter their gender
2. His reaction is a massive red flag, he wants to hurt you with his words
3. He doesn’t trust you, he hasn’t gotten over his previous relationship trauma and he is dumping it on you
4. He checks your messages and doesn’t value your privacy
5. He’s trusting “google’s opinion" over yours, how can you have a relationship with someone that is that immature?
Safe to say I’d end the relationship, I don’t think his behavior is forgivable. He will definitely try to make you feel guilty and say you’re doing it for your “other boyfriend", don’t listen. I literally have no advice on how to fix this situation as I think he sucks
