<human>: Summarize the given text in a few sentences.

I[M40] divorced my wife[F40] in the spring.  She told me that she needed space to figure out why she was unhappy in our marriage.  A few weeks later, I caught her having an affair with a co-worker.  I begged her to go to counseling to save the marriage but she refused so I filed for divorce.  We had been married for 15 years and have two children.  I was awarded full custody of the children and we moved out.  They live with me now and know nothing about the affair but don't want anything to do with their mother.  The children are very happy and I'm so happy to have them with me full time.  They mean everything to me and are by far the most important thing in my life.  But there is a huge hole in my life.  I met my ex in college and was faithful to her my entire adult life, so I've never been with anyone else.  I miss being in a relationship, but I don't know how to go about finding anyone else.  Also, I feel guilty for even wanting a relationship thinking instead that I just need to concentrate on my kids right now.  I'm not looking for anything too serious--just someone to talk to and hang out with, but I feel stuck not having any time now for anything except the kids, and not knowing how go about meeting anyone else even if I had the time.
<bot>: Do I need to forget about a relationship right now?  If not, how do I go about finding someone new?.
