If she offer to bring you along while she's out with them, then it's still ok.

But it felt like her ex-bfs especially the one that took her virginity seems to have some sort of blackmail on her, because she can't reject and must help the man sell Takoyaki to Uni Students.

Also the fact that she didn't offer to bring you along to meet her abang angkat on Christmas seems a bit fishy to me. Mostly likely her ex-abusive guys still have a hold on her, because she kept having to beg you to give "permission" for her outings.

You might need to do some investigation on this, because it felt like she had no choice but to cater to her exes biddings despite she being in a loving relationships with you. She might be being threaten rn by her exes, and she had to follow them or else they might leak stuff to you, which cause you to dump her. At least, please talk to her, because she might need your help and protection on this.
