someone with the confidence to pursue is a turn on .... but someone who pursues through means like stealing your identification, showing up at unwanted times, etc. that's not confidence, that's control issues slamming into place .... just because he was nice enough in the past about it, doesn't mean he'd continue that way ..... things like this tend to escalate .. not diminish .... better to take the safe road on this one I'd think! and just because it took him 4 years to contact you doesn't mean he hasn't been in the background monitoring or gathering info. Not trying to be an alarmist, but stalking has too often been a LONG-TERM thing, if it went for several months, it could easily go to several years. Above all .... don't let him push you from a place where you have established friendships, etc. or isolate you from others!
