My military husband cheated on me 1 year ago in his office and at a Christmas party

Ok advice welcomed because I’m losing my shit bc men ain’t shit.

I’m an active duty spouse w 3 toddlers. Just found out my husband cheated a year ago. Had a whole affair.

I’m in nursing school right now and still have till 2028 and I’m using his benefits to go to school and he is the provider because I am a SAHM and go to school full time. However, my kids are still little, they all go to elementary school.

Details:
They sexted
He gave him H**d in his office
A month later had s*x with her after a Christmas party for his job.

He flirted up until we had to move to another state. But supposedly nothing else happened.

Soooo idk what to do. I feel so stuck. But I need to do school so that I can have a career for my kids. But also, he’s love bombing me right now and idk how long it’d last for. Now he’s saying he will do anything to work on us no matter how I feel.

Anyways, I also have a lot in my head of comparing myself with her and how she looks and if she was better at having s*x and h**d than me.

Any advice for anything is better than being alone with my thoughts.

I have a lot going on in head. I just don’t know if I should think there is also more that went on… but also am I smart for staying to obtain my school benefits? Idk. Tell me yall.
