My children don't love me, but it's alright

It's been a year or two now they've been pulling away.  The older one used to talk to me alot and we shared a lot.  Now she talks to me now and then but mostly she just puts the camera on the babies so I can look at them, she doesn't interact. I keep asking myself what made this happen.  It must have been something or lots of things I said or did, or maybe it's not my fault.  It really doesn't matter. The younger one has told me she doesn't think I was a very good mom, I let her down in many ways.  Stuff I thought I was trying to protect her, but she didn't think so.  At first I tried to keep in touch, but they won't answer their phones or my texts, so I cut that out, I figured I should quit bugging them.  It's been very painful and confusing and kind of heartbreaking for me, but at last I'm feeling that I should just let it be. So this is my confession.  I want to mark today as I am trying to let go.  Let go of the pain, and the need to call them or hear from them.  They have their own lives, I guess I better move on with mine.  I have a great hubby and a cute little dog.  I'm going to stop beating myself up over this and try to let it rest.  With Christmas coming they say they will be here for a day or two.  I hope to make it go smoothly.  Thanks for giving me the opportunity to write this down and get it out. Glad I said it.
