I'm so sorry...I know it must hurt.

It's cruel of him to string you on for so long.
I would echo the advice given already...not all men are like that.

Don't give up hope on us just yet, though I think you are being wise in taking time to work on you and to give yourself some time to heal.

I hope when that time is up you come across an amazing guy who'll disprove the notions given by your ex.
That does remind me...respectfully, who is your ex to make those assertions about the whole anyway? Those sound to me like what the individual wants, not the whole. Don't let him speak for the group.
I wish you all the best, and I hope that you feel better soon.
Hugs,
Harley
