one time i was hit on by a guy i liked at work. i was really interested in him, and i said no because i had a boyfriend.
oh.. well that complicates things. yeah, maybe that will make you seriously examine things. i think you are okay as long as you do not do anything while still in a relationship. but if you feel your current one is lacking something, and your eye is wandering, you owe it to yourself and your current boyfriend to reflect on why that is, and if there can be improvements, or if you should both move on.
i really should not because i have a serious boyfriend.
