Mini rant

Courtney🤘🏻 • I just want to cuddle my boyfriend and pet my cat. 👫🐱
This could get long and will probably be all over so just hold on... 
So lately I have really been struggling with my boyfriend watching porn. I used to watch it BEFORE I got with him, so I know what most of those girls look like. We have not been as intimate as we usually would for a number of reasons, he works full time and is probably tired, and most recently we were in an accident so we no longer sleep in the same bed until we are healed.
I have caught my boyfriend watching porn and masterbating in bed to porn with me sound asleep beside, and now he will watch porn, and masterbate in the recliner while I am beside him. 
He try's to hide it a little bit from me but I know him better than he thinks and I know when he is. 
I one night had a dream of him telling me he would rather masterbate than touch me, I woke up in tears, then looked over to find him doing it. I cried even worse. I quickly left the room and didn't come back for a lengthy amount of time. He texted me asked me where I went and why? I then said I needed to get out of the room cause I was uncomfortable. He didn't catch on to why, so I just dropped it. That entire day I felt so unloved and heartbroken I spent most of it crying. 
Now today, I went out with my dad for an hour or so, and come back to find a gross towel on the couch where I sit, I knew exactly what it was used for and I just put it back on his chair. I then had to google something on his phone and found all sorts of porn cause he didn't shut any of it down. I didn't know what to do so I just didn't tell him I knew. 
How do you ladies think i should go about telling him?
