Porn addiction

Dumping my boyfriend bc he won't stop watching porn. This has been ongoing for months. Days he is away from me he doesn't go to sleep. Two days ago he watched for 4 hours until the sun came up ☹️ He doesn't respect my feelings and he lies about it but I don't let him get away with it.

He tells me every guy watches porn and have fun finding one who doesn't. This relationship has seriously messed my head up, how I view men in general and I don't think I will trust anyone for a long time. Has anyone dealt with something similar? Any advice or input would be appreciated.
