I text other guys behind my boyfriends back (24F)

My boyfriend has been working a lot lately. I love him but I’ve been at home alone bored by myself, so I began texting other guys to pass the time. I never meet up but enjoy flirting and receiving compliments bc it makes me feel good. I feel shitty for doing this to him but also don’t think it’s that bad since I don’t actually meet up with them.
