Husband porn addict and pathological liar

Hello,
I need some help. 7 months ago I discovered my husband is a porn addict. He started going to therapy as well as myself. He recently thought he was ready for a cell phone again. I had no problem with it until a few days in he was using more data than I had in 3 weeks. The break down said he majority was video use. He lies to an extent where I think he believes he's telling the truth. I know that I have co-dependent tendencies. I just looked tonight and while his data usage is low, his video use is 42% of the usage after he promised me he wouldn't use anymore video. Anyone else going through but this?!
