Advice would be nice from an unbiased standpoint

I’m in an almost 10yr relationship. We have a beautiful 7yr old daughter. He has also raised my now 13 yr old son since he was 3..(his bio dad passsed when he was very young). 2 nights ago my daughter was playing on her dads phone when his stepbrother sent him a text. Our daughter wanted to see if her dad sent any pics of her to him.(he’s never met her or me or been around and just popped up outta nowhere) so as she was looking she said “eew mommy daddy’s got boobies on his phone) I took the phone and proceeded to look...the caption read this is what I was doing in Daytona during bike week..the images were of 2 naked girls going at it. I’m pissed and I’m hurt. I can’t even look at his face. It’s like I don’t even know this man that he is trying to portray. There was so much pride in disgusting behavior. My stomach physically hurts. I confronted him and he said who the fuck cares about pictures? No apology nothing!! He has been sleeping on the couch since the other night and honestly I haven’t said more than 10words to him since. What am I gonna do? I’m a stay at home mom. He supports me completely financially. Am I overreacting?
