Now - she is saying I need to wait to date, I'm not ready, I need to spend time alone and that if I'm not dating with the intention of marrying, I shouldn't date. Also that I need to just have female friends. (I almost threw up. I felt judged and controlled).
Hope there is no way in heck you have to only date with the attention to marry. That is ludicrous. If that was the case I would never date again because I am pretty sure I will never marry again.
If I am being totally honest I get the impression that you are still attached to your H. I am not judging I was too for the first year of D. You probably are not ready for a relationship but it doesn't hurt to meet new people.
I feel with dating you have to try to know if you are ready. A sign that you are not is if you compare everything about the person your with to your ex.
Looking back I would say I wasn't ready for at minimum a year and a half probably two.
As for bad advice I would kindly say "Thank you but I am not looking for any advice".
