You said it exactly....you deserve better its about putting a value on yourself and I think you gaev you ex all the help you could but no one can fix anyone that doesn't want to be fixed and it sounds like your ex has pushed his own self destruct button. Ktbelle, you can do no more now only focus on yourself and your needs. He will soon get his life back on track, maybe this is the wake up call he needs to realise what he lost in you- a caring and loving girlfriend
Whatever you do don't feel any guilt or remorse for breaking up because you are rightly looking after yourself!
IT hurt like hell when she moved her new girlfriend in straight away to know that had no respect for my feelings whatsoever but they have now broke up because she cheated on her too so at least I wont take it personally as it seems to be a pattern for my ex but thats her issues not mine thankfully and I am lucky I got away but the pain is still very much inside of me. Somedays its too much for me and I get overwhelmed and scared of being alone but then I think of what she did to me and its ok again.
