Thanks, everyone.
(Hugs for everyone)
I'm doing better now. I know my grandfather isn't suffering anymore. He had a stroke and died a couple months later. At least my family and I got to spend the time with him that we did. Far too frequently in the past couple of years did my ex or I know someone close to our ages who suddenly passed away. Far too often have I seen parents grieve the loss of a child.
As far as relationships go, I am glad that I didn't marry him. I don't think I'm ever going to get married. Even while engaged, I had a very cynical outlook on weddings and marriage. My parents divorced during my childhood. Getting married and starting a family never were things that I dwelled on or dreamed of. Being happy with myself is all that I've ever wanted.
I used to be unemployed (damn you, recession!) despite being a college grad. I started applying for seasonal jobs in retail. When handing an application back to one place where I used to work, right there at the counter was an old friend I worked with. He did a double take and gave me a big hug. He asked me to come back and pay him a visit, which I did. The next time I saw him, we exchanged phone numbers, and on the phone that evening, he asked me out. Things are going well with him.
I ended up getting hired with the same job I had last time in a different location. This new place is much better. I proved my worth over the hectic holiday season and am now a permanent member of the staff. I am now looking into some other part-time job or internship that is more closely-related to my education and what I really want ultimately.
