It was my fault entirely.
She was the best thing that ever happened to me. Least demanding, frugal with spending, understanding.
I was just used to romanticism that I see in cinemas and expected possessiveness and more talkative.
It was also during covid, we were long distanced and couldn't meet due to Lockdown. I had gotten new job that took lot of time from my day. We used to have fights and after a while, I just gave up trying in the relationship and I was with guilt that she deserved someone better, who had figured out his life and I ended it.
If I knew then what I know know about relationships, maturity etc, I would've never let her go, would've met in person, sit together, solved problems. Truth be told, I indeed was really happy (effect of oxytocin) in that relationship, just was immature then to not realise that perfect relationships don't exist and it's our duty to make it work (it's not gonna work out on it's own). And also, we don't need to be perfect in relationship, we just need love and understanding.
