the way I see it, its better to have someone who is liberal than overly possessive. now suppose he doesn't care anymore, then too its better at least he is not trying to dictate whereas the possessive ones cant let go off the control even when they dont want anything to do with you otherwise. of course there is a difference between letting you live your life and not being concerned at all, only you can tell the difference. i faced the same about a year ago but guess what:? i couldnt understand when he fell out of love with me and i kept thinking i should he happy that he doesnt interfere and lets me live my life. i used to have these little doubts that i used to brush away... anyway i hope things turn out differently for you, as it is you will know soon enough.
(and you wonder why men can't figure women out)
