Sorry for your loss

I have had this happen too. Kristin died of ovarian cancer in 2010. I cared for her daughter and youngest boy after she died.
Their dad had run off when the youngest was born. I've cried a rainbows worth of tears. It doesn't get exactly easier but life becomes more tolerable over time. ((Hugs))

Be gentle and kind to yourself. You’re grieving, it takes times d there are stages of grief. You’ll fluctuate between them, totally normal. Keep talking. Find your support system and lean on them. Take as much time as you need.

Damn. I've had imaginings about losing a lover and I can imagine how I'd react at the loss. Sadly, I've never had a lover to lose.
I know that it's the last thing you want to hear right now and I hate when people tell me that I'll find someone much in the same sense. There is someone else out there. They won't be her and you shouldn't try to compare them to her. They will love you just as much as she did and she'd be happy knowing that you're in good hands while she's not around.
