The only person you are failing by staying with himis:You.
Many of us have bad pickers, what we need to do is work on us, discover why we make these bad choices.
Could it be because of our past, monkey see monkey do.
Could it be because we have low self esteem.
Could it be because we have a co-dependent personality
It could be a number of things, time for you to find out what it is. Time to break the cycle.
