I am 40. Yes, it's not out of the question now, but it becomes increasingly unlikely the older I get (I have several friends my age and younger who are having real difficulties TTC). I have 2 children that's true, but I always intended on a 3rd - I left my Ex in part because I wanted another baby but not with him.
I am out and about all the time, as much as it is possible to be with a full time job. I am lucky in that I have lots of friends to socialise with. I do meet men in real life, but with as little success as online.
I tried taking a break from it all for an entire year in 2010 (decided online wasnt for me and I would meet someone in RL instead). I met absolutely no-one.
I'd like not to feel depressed about it, but year after year passing, and nothing changing, never getting a second date, is horrible. I think anyone would feel down in my position.
