Advice needed asap

I am 25 weeks pregnant with my 2 child with my husband. We have married since October but been together for years prior. We also have a 4 year old daughter...

So I have been feeling like 💩 lately because this pregnancy have been beating me up physically or emotionally.

Anyways I had a feeling my husband was doing something sneaky.. so I went through his phone to investigate and I find out he has an only fans and been messaging women about there sex videos and supporting there pocket by buying there videos... I don’t know what to do or how to feel .... I just know I feel even more down about myself.

How should I come to him about this ?should I just leave it alone ?

I feel like it different than watching free porn because he is actually communicating with these women and telling them there sex game is nice.
