Forever doomed

I'm 27 years old- wasted five years on and off with my ex and still today trying to let go (which has gotten easier then what it was year or so ago) but through out the years I STILL haven't found someone else and they always say let go of past and something else better will come along...tried...Still nothing. What's wrong with me??? Same time I won't settle for anything or just be with anybody out of lonliness NO WAY! ....Ex is a comfort thing but realize be nothing more since we fight to much and I'm not getting any younger but older...need to figure it out...wish it was easy for me like it is with some woman today finding a good man right away. *Running out of prayers with this...* but I know must continue to stay humble but mannn....what if im only good for my ex and nothing more (as it seems) sigh😔 deep down I can't do it anymore with him.
