Guys, have you ever been abused by a girlfriend?

So I was talking with my crush and I asked him out & he said no.

He then went on to tell me about his ex girlfriend. Who was emotionally abusive & he didn't say physically abusive, but do you know how you can tell. I could tell. When he talked about it he clearly got emotional & then tried to cover it up by saying mean things to me to deflect. He then brought up she was the same ethnicity as me & he just couldn't accept my date. I told him that I was sorry for how she treated him & he didn't deserve that. He should never answer her messages again and if she gets pushy get a restrating order.

Now, he's still really helpful at work. He's always doing stuff for me, helping me, saying hi, nothing has really changed between the two of us. He clearly felt like he could open up to me & I offered him some therpy resources if he decided that he needed them.

I guess I don't know what's going on here, I don't think it's over and I am talking to someone else rn just as an attempt to move on. But what do you guy think? Is this over, should I like... be worried about his mental health?
