Your sister sounds like me. I broke up with my bf of 10 yrs (we have no kids) and it was very painful because it was my decision. It's been almost 5 months of being single, I do feel so much happier don't feel controlled. I am still learning and re-discovering myself, I said a long time ago before meeting my now ex that I wouldn't date again.

Right now, I don't even want to date. If I wanted to, it'd be casual/short term on my TERMS! I was torn by my ex how he put another girl's feelings before mine yet he went back to her so they can be friends. He kept her on the back burner now she has a bf in her age group gee what did that say about her! He still has her on his friends' list she just wanted a daddy.

Sounds like your sister is on the right path she wants to take care of herself, her own emotional needs nothing wrong with that. God, I wish I could travel with friends when I please! Right now, my main concentration is getting a full time job and moving to another city that's it then everything will settle and I can work on other things.

Our society acts like it's the end of the world if you aren't dating/married or having someone attached to you - I consider our society to be very codependent.
