I've been through divorce. As a matter of fact, my second attempt was made after my husband separated from me, and was living in an apartment.
But I didn't succeed, and it was odd because a friend of mine and my mom called within minutes of each other, after I did what I did and left messages. I answered as my mom was leaving her message and told her what I did. I didn't really want to die, but I just didn't know how I could go on living with so much pain inside.
It took a very long time to get used to the idea that I was no longer going to be with my ex-husband and I went through a grief period. Now, I hardly think about him. But we didn't have any children together. We were married for about nine years, and dated for seven years before we got married.
I know with the children that you have, you will have a hard time not thinking about your ex. But trust me, over time things do improve. You just have to be able to get through this tough transitional phase, which is the absolute hardest time in the divorce. You feel like your heart has been ripped out of your chest and stomped on the ground, shredded to pieces by your loved ones, and it's hard to imagine how someone can be so callous and cruel, a person who you used to laugh with, someone you thought had your back and you had theirs. It's the ultimate betrayal. You learn not to trust, to put up barriers and harden your heart to protect the core of you, your self preservation. You also find other ways in life to find meaning and in those, you find your will to live. Some days you just want to stop existing, and then there are days that are somewhat better, until the time comes that you are finding yourself making goals again, and looking forward to little pleasures and feeling gratitude that you are still alive.
