What do you expect from your partner?

What actions do you think your partner should take after finding out they’ve cheated. (ONS)

I found out 6 weeks ago, 3 weeks ago we had a planned holiday so we both went on because we wanted to reconcile. Before going away I feel he was saying all the right things.. wanted to rebuild, will try his best, has a lot of work to put in. Since that holiday (it didn’t go 100% planned for obvious reasons, some arguments) he says his heads a mess not sure if we can work through it. There has been a change in his previous messages before holiday to now. I don’t know if I’m expecting too much? I don’t know what I need to expect - I’m confused.

I asked him questions the other night and he was a little defensive saying he’s answered them multiple times before. He doesn’t see himself doing anything wrong but I feel like I’m expecting more remorse. I don’t really know how to explain it.. he’s says he’s not going to do anything more than he’s already doing.. I’m not expecting flowers every single day or anything like that but I just feel like I can’t talk and it’s got to be swept under the rug type thing. If I was the betrayer I would be doing anything and everything I could to make things better.
