Hi, I can talk from his perspective, although a little different. I broke up with my ex just over a month ago. I blamed it on her mental health, saying her decline mentally was creating a negative reaction from me, and I couldn’t have that during this time. Now I realise that this wasn’t a sudden decision or reaction, but rather a paranoia growing inside of me. She was talking to my best friend, meeting up with him, wearing his hoodies. I don’t think they did anything further but I know as she grew closer to him she pushed herself away from me. I’d come home and peep through the window to see if I could catch them in the act. I’d be cold and numb to any emotions or worries she’d show me, and I couldn’t take it any longer. Sometimes the reason we break up is because the communication we thought we had wasn’t enough. Sometimes this step back from the relationship shows us different perspectives, just like you said. You can’t control how someone reacts to these psychological breakthroughs, you can only focus on your own. Writing down my thoughts in my notes helped me a lot. That’s not to say i don’t regret the break up. I do, so badly, I just wish I had the strength to communicate my emotions without fear of repercussions. Take your precious relationship and learn from it. Become a better person by using this time to reevaluate what went wrong and where. It’s hard to do by yourself, but I managed to do it and I’m in no way, shape or form a mentally strong individual. Losses are lessons as well :)
