<human>: So I've been through some pretty rough times this year. I'm thriving for the last few months. I'm 23 and after ending a six year relationship for nearly a year and a half ago, I'm still learning to forgive, forget and let go of a huge anchor in my life (if this picks up I'd be glad to elaborate into my story). The thing is, I know I've got some pent up anger, but I try to deal with it as rational as possible, when I'm happy I'd just like to ask my ex if she's happy (she's with someone else for a year now). I have no intention of getting back together, I've haven't spoken or heard of her since march. Anyways, I'd really like to know if she is happy and thriving as I am sometimes, on the other hand I don't want to pop out of nowhere and mess her head up. I would love to hear from her she's happy, at the same time I feel it's better to just let her be and stay as total strangers.
Redditors, I'd appreciate some advice, and some experience in the matter. For most of the time I just want to stay away, on the other hand, I'd like to hear she's sincerely happy from her. I've grown to accept us parting ways, still It would be really comforting hearing from her she is happy. But Im reluctant to popping out of nowhere and bringing up the pain she's been through our breakup. 
If you've come this far, thanks for reading.
