I need some advice as I feel I'm ruining my relationship if not have already ruined it. I've been with my partner for a few years now and he really is amazing but I have a bad habit of sabotaging anything good in my life. I don't do it on purpose I dont even realise I'm doing it at the time. I honestly know deep down i have abandonment issues and this is what causes me to be the way I am but I'm at breaking point. I constantly fear him leaving me even though he gives me no reason to think this, I overthink and look into everything and it drives me crazy. I know I'm going to sound mad and I would agree with anyone that says it but I just dont know what to do anymore. I always think I'm going to be left or cheated on or that if my partner doesnt call back or text back or if he takes his phone everywhere with him that there is someone else. I never think I am good enough and end up pushing him away with my thoughts. I sit there putting situations in my head of him leaving and I constantly think he doesnt want me that I'm not good enough he just stays with me out of pity. Its like I need constant reassurance that its okay and that he wants to be with me. I get this isnt a healthy way to be but it feels so out of control, I say something stupid or tell him I'm worried about him leaving then regret ever saying it as I know all I'm doing is pushing him away. I feel awful as he doesnt deserve it and wonder if maybe I should end it to save him the hassle of it all. The worst part is I know hes not cheating I know he loves me yet I still cant shut it off. I do this with family as well but not to this extent. He gets sick and I think he is dying. I know right, crazy. But tonight I've done it again, I've caused an argument over me overthinking his friendship with someone and now I wonder if I've gone too far this time. I dont want to be like this anymore but I also dont know what to do. I've spoken to him about my worries but not actually how bad it gets. I feel like I'm constantly fighting a battle with myself. I love him so much that I'm scared of pushing him away and dont realise that's exactly what I'm doing before it's too late. Should I just walk away and save him the hassle of being with me?
