That has been my situation as well. When a friend has a boyfriend, you are suddenly dispensable. I am married but the loneliness of not having someone to vent to occassionally, or just to share things with...to laugh, find things in common and to visit...just nothing like it.
I have recently moved to a new town in another state from all of my friends and family. I currently am staying home but looking for a job and it just gets kind of lonely without some female chat time. Sometimes it is just nice to open the mailbox (either online or the snail mail box) and get "hi there" without it being spam or bills!!
Any time that you want to chat, let me know.
