re: my ex left me again and its tearing me apart (Please give me some advice/insight)

1st off. It sounds like she needs space (because she is crazy and has to "figure things out") and you need space because you are too attached to her. You have an abusive relationship. If she doesn't care for you, and it doesn't sound like she does, then why put the effort into her? It's best for everyone if you just move on. You need to get as far away from her as possible. There are too many good women out there to worry about one as selfish and cruel as this one. You need a healthy dose of confidence and reality. Move on. Move on. Move on.

She will never be trustworthy. She will never stay faithful. You will always be worried. She has no respect for you. Become confident and you'll get a woman quite easily.
