Yes,looks like you are too sensitive!
If i were you,i would get to know her first,find out if she is to be my wife,best friend for life.Not get too physical right away,a little bit is allright(used to do that(would not do again) and now know that that added part ALWAYS changes any relationship)Feelings become blurred,avoid unnessary pain and confusion.Once you are sure about her,theres the rest of your lifes for that!
Try not to hope 100% on this lady,80%or whatever ok,a little part of your feelings should be detached(hard,but can be done)if she is the one,Great,if not,thats ok also,knowing theres still waiting something better for you out there,and also know you are never alone!In case she askes why your holding back(if you are)always be honest,and tell her you want to get to know her first.Anybody would understand that,and speeking for myself,appreciate that.i am a woman myself.
