Need Some Encouragement

Okay so I recently found out my boyfriend cheated on me again ( Sexting). I mean there were 5 different females in his phone. Let’s roll back to last year, I was 2 months pregnant with our daughter when I found out he was sexting a female. Fast forward to this week , he’s sexting the same girl plus 4 other females. The crazy thing is , they all know about me and do not care. He sleeps next to me every night. I have so much mixed emotions when it comes to him. He tells me he loves me , and it’s hard to believe when he did all of this to me. We have a 5 month old together. I think to myself , what example would I be setting if I keep brushing it off and forgiving him acting like nothing happened. I also think , what example is he setting for our daughter if he’s doing all of this to me. I know what I need to do when it comes to us. However , I just need a little encouragement I know I deserve better , and I’ll never trust him again. Anybody else in a similar situation ?
