Breaking up with my bf

I just found out my boyfriend sexted a girl online via kik. They have been in contact before we met but since we’re together they rarely have texted until last week, when he asked her for a nude and sent back a d*ckpic.

He has done stuff like this (or worse, like sending explicit photos of me to his friends without my knowledge) before but now I won’t let it slide anymore. I’m having trouble with self worth and respecting myself in relationships because I’m just so used to him being around and I don’t know what to do alone, but now I’ve had enough. Tomorrow after his work I’ll break up with him.. I’m really dreading this. Right now he’s sleeping in my bed but I just can’t get myself to wake him up and kick him out. I still have stuff at his place and it will just be really complicated I fear..

Some uplifting words would be well received right now.. 🥺
