Marriage and parenthood

I took a long break from social media and I'm back. Married and i had my baby girl last July. Since then a lot of things have happened. My husbands ex sent him nudes and asked him for a three some. During my whole pregnancy my confidence went down a dark rabbit hole because he looked at porn a lot. But after I had my baby he and I talked and both agreed to just do joint accounts from now on and to keep our phones unlocked for each other and that we will no longer keep any secrets.
