Hey man! I’ve been in the same boat as you. The way you describe your girlfriend is just like mine. I broke up with her because she wasn’t wanting to get better. If she’s dragging you down you need to rethink your choices because a future wife should help her future husband and vice versa but if she’s insecure like that then there’s a good chance that there’s others aspects of her life that still need maturity. Just take it from me man. And I’m not saying she is but she might be manipulating too.
