Edit: crosspost from asktrp. Looking for a different opinions.

Alright guys. You will read the first paragraph and think that I should next her on the spot. I get it but please read the whole post. The thing is she's fuck-yes about me. I'm looking for real advice, not from fake internet alphas.

About me: SQ 160 kg BB 115 kg DL 200 OHP 75 kg. 95 kg BW around 15 % bf, college,attractive, with plenty of options

I've recently learned that my ltr (close to a year now) is still in contact with her ex boyfriend. I wouldn't care about this one if she wasn't responding to him - there are other guys that send her "I miss you" texts from time to time that she ignores. What's more alarming is that she was with this guy for a little more that a month while on vacations - they parted ways when she got back to our country. Good news is that it's always him texting her and she rarely responds (once a month maybe). She trusts me completely and leaves her phone with me, so I've seen some of the messages. It seems that they've met exactly one year ago and the guy is sending her some clingy texts. She asked him about his life and said that she I extremely happy with me, life is good etc. Although somewhere she mentions that she doesn't regret parting ways she thinks that if they didn't it would be great too.

I still don't care to much - she's always been submissive to me, takes care of me, pays for me, cooks for me, fucks me good, was generally very invested in me from the beginning. What's more, she is submissive to a point where she fantasies about me fucking other girls in front of her and even made Tinder account to find girls for us. She compliments me all the time in front of her friends, family, everyone. She believes she is lower smv than me.

So although I don't really care, I think that it is disrespectful as fuck. I know that boundaries are not sexy but I feel that my frame is strong enough to pull this off. So my plan is to tell her that I don't consider it healthy to remain in contact with exes. She can do what she wants but either way there will be consequences and she's responsible for her action. If my gut will warn me I will drop her on the spot.

I'm also thinking if I am not giving her enough comfort - we fuck really rough, almost every time dirty talk is about other women. She knows I flirt with girls and get hit on by them ( the best one was when she walked in on girl asking for my number). So maybe this ex is some holiday romantic cliché (he's Italian, they've met in Barcelona etc), and his clingy "I think about you" give her feels (while I mostly tell her that I will fuck her good in the ass).
