Need advice on husband masturbating to other girls

Hi everyone, I need advice on what you would do 😔

My husband and I have been together for 5 years and have a three year old daughter and are currently actively trying for baby #2. I have pcos so I am taking medication everyday to help me conceive.

Well, this morning I walked in on him in the bathroom sitting on the toilet. He quickly covered himself and turned off his phone screen. (Yea I know 😕) I’m not dumb so I asked to see his phone and he refused.

Tonight I went on his TikTok history and found all of this. I know he was watching girls when I walked in on him in the bathroom bc under one of the headings it said “yesterday “ and it’s currently 2am.

I can’t help but feel ugly, unwanted, disgusted with myself and him. No clue how to address it . I know he is masturbating to these girls. Honestly if that is what he wants to do I almost just want to tell him he can do whatever he wants I don’t care. This isn’t the first time I have caught him doing this. Below are the screenshots of his watch history . Just looking for advice on what you would do/feel?

(It won’t let me post the screenshots, only 1. )
