My husband watches to much porn

I’m posting this because i don’t know if this is common or not my husband watches porn and it makes me feel really bad about myself I feel like ever since I lost my baby girl he hasn’t looked at me the same. I had caught him about a year ago watching it and he told me he wouldn’t do it again and last week I found out he was watching it again because we had gone 2 weeks without any sexual contact and it was strange so I looked on his phone and found out that he was watching porn again and that’s why he wouldn’t even touch me. I want to know if it’s normal or should we see some couple counseling or should he just go see a sex counselors?!?! Help!!!
