My ex-boyfriend who I had lived with for 7 years hanged himself a few months after I left him. That was 15 years ago and despite being married to a wonderful man (who is the love of my life) there is not a day goes by when I don't think about him.
It took me about 3 years to start to get over it. Time really does help.
FrozenYoghurt - I would just be there for her to talk to. Be prepared that there will be various stages of grief and some won't be pretty. When someone kills themselves, people don't just say how sad it was that they were obviously so unhappy.
I know that there were times I was shocked just how deeply I hated him for what he had done to me, his mother and the rest of his friends and family.
Some of my family decided that it 'wasn't nice' and refused to mention his name again. We had shared 7 years of our lives at a young age and it was impossible for me not to mention him. It was doubly hard having the awkward silences.
The first few weeks are the worst - I couldn't sleep and finally ended up taking benzos just so my mind could shut down for a few hours. And then things get bad again later on when the initial sympathy from people has worn off and you are expected to be back to normal and moving on.
My heart goes out to everyone who loses someone this way. It is one of the worst ways to lose someone in my opinion. I know how I felt - and this was a man I had just left, not a parent, not a husband, not someone I had children with, and above all not my child. I cannot begin to fathom how a parent must feel in this situation - it is one of my greatest fears.
