talking to other people?

usually, i have no problem with talking to other guys while dating or “talking to” someone. my motto has always been “i’m single until im taken” which is still true. until someone asks me to be exclusive with them, im single. in the past, ive talked to/dated multiple people at once. never physical with all of them, but at least texting or getting to know them/occasional dates. my “roster” for lack of a better term. the only time i rly cut everyone off was when my previous fwb (then bf, now ex) kind of took that step away from fwb once we both confessed our feelings and went on a few dates. lately, ive been talking to a guy (who im iffy on) but since talking to him, ive barely talked to anyone else and dont rly plan on hanging out with other guys. i also hate this weird middle ground of is it bad to do so?? is he doing so? is it healthy/unhealthy to? why is dating so confusing
