<human>: Okay so, we've been together for about 2 and a bit years now. At around the 6 month period I snooped at his phone to see that he was being a complete dick. I know I was in the wrong by snooping, but I questioned him about it and he said he would stop. So me, trusting him, let him go on being himself. I soon realized nothing had changed at all, but this time it started getting a little worse. Sexting other girls, asked multiple girls to be his girlfriend whilst with me for around a year. 
I for some reason just kept pushing it aside like it was nothing because I feel like somewhere deep inside things will change.
I recently moved in with him and his parents. I did so thinking he had changed enough to take this relationship serious enough to ask me to move in with him. But now 2 and a bit years things aren't any better. I feel like all my trust and hope for him is slipping.

<bot>: Girlfriend not sure if things are going to change, scarred about trust and hope slipping. And afraid of losing everything.
