Hi guys.
I have a relationship around 7-8 months. He behave me really nice. My all problems he tried to solve them like his problems.
He was drunk and I got his phone, I see some messages from someone. She send kisses , her pictures hugs.
I read all messages. She always say how much she loves him. He behave her badly but he was still talking with her. And he send her money too.
I asked him about her. He apologized me and he said it was not important. He cannot lose me for this reason. Blabla.
should I give him a chance again? He can be change or not?
