girls hv lot of choices and not like guys they hv back ups in the name of best frnd caz anytime their best frnd may turn into boyfrnd and boy frnd will be thrown out so guys need to be aware than. girls and in case if they found any activity changes with their gf even they like it not u need to talk politely. some may jump from earth to sky & some times genuine reasons will be there but if it keeps repeating guys need to be prepare to face it & to find the right one who cares u really. u. can’t sit and feel for the one who don’t caresI think my advice also applies for girls too, don't be too available to your bf, he will take you for granted too.
