Thank you for your responses, both private and public
I wanted to update my situation for those who were interested. We have decided for now that we will remain together and see how it goes. Although that sounds a bit wishy-washy, there are many things in our lives together and in our family that work. Logically, our coupling makes sense. No relationship is perfect right? You take the good with the bad. Marriage takes work.
Although ideally I would like to be with a partner who is more interested and in love with me, it is something I am willing to forego for now. Who knows even if I would ever find that kind of love anyway. My husband is at least a good provider, and an excellent father. Leaving that may be foolish at this point for some pie-in-the-skye idea that may be somewhat of an adolescent fantasy anyway.
Thank you for your input and thoughts.
