Cheating...

I'm divorced... I have a bf or SO .... Whatever you want to call it.. I love him very much.....We are happy but in a bit of a dead end rut in our relationship... I think we need to work on things to move us forward he wants to slow down... This male friend of mine messaged me out of nowhere and we started talking..... Nothing seriously just general small talk... Well long story short our small talk switched gears and we hooked up.... Things is I don't really feel bad about it.... What's that mean?
