[Always *]

I dated a guy for 3 days one time. Just know you're doing better then that and it'll be ok. Loads of people only date for under the 3 month mark and there is nothing wrong with deciding he's not the guy for you. In fact, it makes sense that you originally thought you liked him and are now realizing that he's not the one for you; that's typically something realized early on, not down the road (down the road is usually dramatic upheavals of some kind). You're on the right track and need to do what's right for you
