When a girl is trying to monkey branch me (get me to stay in a relationship with her since I am the best option as a "provider", whilst she fucks other dudes) is it okay to just fuck them without making any sort of commitment or investment to any kind of relationship and if I could care less if she's fucking other dudes?

I'm struggling to see any negatives: I'm fucking the women, whilst she isn't getting any sort of relationship or validation out of me.
