Christian husband watches porn

Superblessed🐑🐝

so, my husband and I are both Christians. I just found out yesterday that he has been watching porn on and off when we get in to little fights. I don't think I would have found out had he not gone limp 3 times during sex in the same day. I actually had a dream that that was why he was going limp so I asked him about it and he admitted to it. I'm not sure what to do, I was so hurt. we are currently trying to have another baby after a missed miscarriage in June. he promised me he won't watch it again but I'm scared he will since I work night shift.
