Do you guys think I did too much and was too hard on the girl?

I found out that my boyfriend was messing with a girl he works with. They have done many things together including have sex at his home, which I consider my home as well because he is my boyfriend. He was even planning a big “special” date for the two of them. They have gone on walks, held hands, they have kissed on multiple occasions. He was even planning on making a routine out of going to the gym with her. He told her that I was just an ex that he got his “rocks off” with and said, before they had sex, that sex with me would stop if they started to be sexual together. When I saw and found out all this just by reading text messages I texted her from his phone and told her that I was the girl he was currently living with and asked if she would tell me what was going on between them. She didn’t respond. So, I texted her the same thing from my phone. She still didn’t respond. Two weeks went by and I still had heard nothing from her until I saw a bunch of messages coming into his phone this morning and from the context of the messages she was responding to a conversation they had in person at work about him asking her to come over after work and cuddle. It seems she was hesitant to say yes. So, she went home and thought on it and that’s when the messages started to come in. She was saying how it no longer felt right to be that way with him anymore and explained to him why she had already put a stop to other things they were doing before she found out about me. Which tells me he was still pursuing her even after he knew she knew the full truth about me. Long story short, I texted her and told her that since she didn’t want to talk to me that she needed to stop texting him because it was like she was considering still messing around with him even though she knew about me. All the things she told him, about having morals and doing what’s right and ending things with him, she could have told me. Her conscious seemed to kick in too late and that was what frustrated me.
