I know too much

Hi everyone I recently just started dating a guy, he’s such a gentleman. We’re both 25 years old and I was dating before him nothing serious.. since then I’ve just been single and we kind of just happened. Met at a party and been inseparable since.. he’s nothing what I’m use too. His communication skills are pretty good, he’s so affectionate with me.. we went to the same school but we never talked and I never knew much about him but I’m familiar with the people he associates himself with.. things is, just this past weekend I opened up to my best friend and finally told someone about him and she dropped a bomb on me. Basically saying she knows of him because he cheated on his girl friend and I guess they just had so much drama. He treated her like a “queen” she never expected that from him, I guess she was completely heart broken and he just got out of a 11month relationship in January.

I was completely shocked, I would’ve rather not known any of this.

Now I’m terrified, in such short time I’ve fallen for him. We talked because I couldn’t hold it in but he said he’s changed and he’s all about me.

I just feel like I know too much.

I can’t help but be sacred now

What are your thoughts?

Edit-

We text 24/7 we’ve been seeing each other every weekend. I kinda want to take a step back because now I’m doubting how “good” he is, I’m so confused. Any feedback is welcomed, thank you ❤️
