I was happy a few days ago until I got treated like dog do by someone I had been dating for a few weeks. And then things went wrong at work and I was undermined and belittled in front of other colleagues. And also had a row with my ex over Little Tiggs.
It could be he's moaning about someone in the family one of our sons for instance, and he's moan moan moan, to me about it and I will tell him to, say it to him not me! He just doesnt seem to get it, and it is beginning to wear me down.
