Nathan and the bbysitter

May be an unpopular opinion but I know Nathan hasn’t cheated on Haley but I do think he’s being inappropriate with the babysitter. Watching her swim naked in the pool, not telling Haley the comments she’s been making to him/ not immediately shutting her down. In my opinion he should have fired her a long long time ago. I’m currently on season 5 ep 7 right after she told him she saw him looking at her in the pool. I just wouldn’t be ok with my husband acting the way Nathan has so far if I were to find out these things I would almost consider it cheating bc why is he letting her play with him? I also have similar feelings to him and Haley’s sister a while back. What do yall think?
