Hi orangyred
Well the way I see it is that feeling ignored while you were growing up
is a
big thing,
can be
deeply hurtful and
can easily lead to a disconnection in feeling love for her........so please don't feel that there is anything wrong with you in feeling that way

In fact I'd say that in some ways it is a "healthy" reaction.........afterall you aren't feeling that it's perfectly fine to be loving someone who ignores you at a time you really need/ed their love...........
Although that's not to say that it's not going to be possible to re-establish a connection with her and maybe love her for who she can be to you now (or at some point in the future)............but only you'll be able to decide that based on who she is now (or maybe in the future) and on exactly what effects your past has (or will have) on you............
But either way.........it doesn't have to be "necessary" to love your parent/s (some parents
won't have fostered/allowed for that!!) to still lead a fulfilling life and to find love and feel love in your life.........so keep your focus on you, hey??
If there's something/anything you can get out of your relationship with your mum now or in the future then great.......but if not there is still plenty of opportunity to thrive without that if you need to.
