Need some advise. Split up from long term partner, DC involved. He has new partner but for months has been saying he wants to come back but does nothing about it. Substance abuse and helpline advised that he could be struggling to make decisions. I am fed up of getting sucked into hope that he will fix himself and we have a chance. I have done therapy for months, read self help books and still struggling to let go. What can I do? Very limited time for dating as have DC majority of the time... thanks
