It seems like girls get incredibly confused around that age 19-22 or whatever. It's like when they're 16, 17, 18 a relationship is all they think about and then after college they want to end their "college romance" and see what else is out there. I would have to agree that if you've been dating a female long term and they're under 24 it's not going to last. I'm sure it's not just females, but I was perfectly fine with my ex (she was a few months shy of 20 and I was 22 when we met), I didn't have to see what else is out there because I had already knew what was out there. Some people don't, so they have to experience it themselves first hand before they can truly be in a committed relationship I think.

You are the one torturing yourself by keep tabs on her through the social media, which is as bad as text/talking/calling. That's not the proper way of doing NC, or letting some one go.

You really do need to let her go completely, and stay off her social page. Its no longer your business what so ever.

But you already know that, yet you do it any way?? Its no ones fault but your own that you allow yourself to be fooled by false hope, and trapped in misery, so let go, or keep being miserable, confused, hurt, or whatever has you distracted from acceptance, and a proper healing.
