Porn in relationship

Girls & guys…. Help. I’m @ a loss.

I was in a relationship two years ago which lasted a year. He watched porn & I was NOT okay with it & he knew it. When he was younger he had an addiction.

I caught him lying about porn. Told me he didn’t watch but I found it on his phone. If he watches it, that’s ok I just don’t want to be with him. I deserve someone who will be honest with me & respect my beliefs. Some women are okay with it but I’m not & my partner should respect that.

We have gotten back together & I love him but I can’t find myself to trust him. I’m a wreck.., full of tears. I don’t know what I can do bc he’s proven that he will lie.

Please help & advise & give me insight on your relationships.
