My partner and i have been together for 3 years with 1 child and 1 from a previous relationship of mine. We had an argument the other day over something petty but it turned into a big row and i ended up kicking him out for the night so he went to his dads. Few days later i find out the night he went to his dads he was looking on sex sites the ones that are like dating sites but just for sex. Hes so ashamed of himself and couldn't stop apologising for what he had done he said it was a big mistake and looked because i kicked him out. Hes promised me he will never do that again or ever cheat. My question is would you consider this cheating? And could you forgive this?
