I'll never understand people that does this.

What happen in your head when you start love bombing someone for 3 months, not standing your partner making new friends, especialy the same sex as you, even crashing out when the partner take care of his friend's daughter?

Crying about losing him whatever way.

All of this to basicaly avoid him over night, saying that this is all his fault.

Admiting clearly you don't love your partner anymore, but waiting for the right time to get out of it thus making it that you won't quit him by yourself.

Then acting like he is a monster that left you without any reason in front of mutual/unknown friends.

Like how can you treat somebody you said you loved, like a dog?!
