Spent some time reading through this thread.
You may find evan Marc katz blog to be helpful. He has some very good, if uncomfortable advice, when you first read it.
The golden rule? Never ever ever message first. Im not saying dont approach on OLD but dont text first after exchanging numbers, dont call first dont leave voicemails. Men will do all the work if they are interested.
Don't do the asking out for the first at least 3 months and don't chase. Men move at their own pace and don't do their jobs for them.
If they aren't acting like you want, move on and don't waste time. It's a numbers game and it pays to date more than one at a time.
Also, some expectations management needed. Men are going to message other women at the same time as you and on the days you date them.
Unless you have healthy confidence and self esteem, work on that first before venturing out.
Good luck to all of you.
