I totally understand how feels to keep attaching to someone and to keep getting hurt, trust me. I was just talking about this with my T last week and even though it will take some work, we can be healed from attachment issues. It sucks getting hurt over and over and over again but you can change this pattern! You just need to have someone who supports you and really helps you work through it. Seriously, don't settle and accept a life you aren't happy with. It's not worth it.
