Husband studying everyday with a colleague he finds attractive

Hi all, this issue has been really getting me down and insecure.
My husband has a female colleague who he is fond of, he says good things about her and has told me in the past that he finds her attractive.
He’s told me that they both have agreed to be study partners for an exam in a few months. They will soon start studying together. He told me at first it will be several times a week then increase to daily. They’ll be meeting both online and in person one on one for months.
I’ve never met this woman and I feel very insecure. I honestly feel like going abroad a few weeks to get away from this.
Any advice would be appreciated

Okay, hell NO. If this is your husband, and you tell him that this is disturbing to you because he already told you in the past that he finds her attractive, and he still goes studying with her: d-I-v-o-r-c-e! Directly. Why would he not consider your feelings, when YOU are literally his WIFE? That’s not a man to me.
