As a suffer, what he said does make sense. He’s said no, he probably feels horrible saying no over and over to you, and yet you keep refusing to accept his no. So he feels like he’s hurting you over and over by trying to keep the boundary that the relationship is over.
When I have had to tell someone no over and over and they don’t accept it, it feels very frustrating and awful. Like I’m hurting them again and again even when it’s the boundary I need to hold and will continue to hold.
Someone doesn’t return to feeling happy lovey dovey feelings if they keep saying no to the someone and they won’t accept it and keep pushing for a yes.
Does that make a little more sense where he might be coming from?
In regards to therapy, do you mean for you or him?
If he does it, sure, it might help his symptoms a lot. Once therapy starts, symptoms often get worse for a time and I’ve know quite a few sufferers who changed who they date and what they want on their lives as they go through treatment. I personally could not date at all the first two years in treatment. It is very hard. For someone already feeling overwhelmed by a relationship, it’s not like just go to trauma therapy and they’ll not feel overwhelmed by a relationship on top of that. For some, it’s too much to navigate both at the same time. It might help him in relationships down the road and overall. It may eventually lower his stress levels and give him more room to have steady stable relationships.
His getting treatment isn’t the fix for him to return to the relationship with you. It may even lead to him holding the boundary that the relationship is over more effectively.
For you, I think CBT could help a lot, especially with your the low self worth and feeling unlovable, and therapy can help work through the fears and nervousness and emotions that you have and are struggling with as you grieve the end of this relationship.
