My ex contacted me because she really likes her fuck body and he does not like her. I don't know how to react properly?

We broke up because I moved very far away (14hrs of time difference). She really likes him because he is a bad guy, hot and really good in bed. (BIG PLAYER). And she wants him real bad een though she is hurt. Also, this guy is spending time with other girls on his birthday. Now, my ex wants to talk about her romance life with me but I get mixed feelings. I don't really know what to say to her. Yes, it does piss me off. I just want to say something mature.
I want to support her but I don't want to be disrespected as "nice guy".

Also, she asked me to text her often beause she is depressed. (She actually said depressed).

She said she liked me because I was very faithful and care about her unlike other guys.

Tell me how you would handle this situation, or how to be supportive without being disrespected.

She is 21, and I am 25.

Update. She unfollows me on instagram after not chatting for 3 weeks. I ask her what is going on. She said a new guy she is dating does not want her to follow her ex. That's fine except that she still follows her ex before me and the fuckbody that I mentioned in my original question. She does not explain why. She says "whatever."

She said she unfollow me because we are done. Does not make much sense to me.

I guess this is what I get for dating a girl not woman.
