Is this an overeaction?

i think you're overeacting. first of all if you really like her just call her ,dont pester her just have a casual chat. go on your next date and see how she acts around you. it would be quite easy to see if she is really interested in you. and while you guys are talking you could just ask her what she looking for . as in whether she wants a relationship or not just so that you both are on the same page. that way you'll know what she is thinking . dont over yse everything and freak yourself out.goodluck
