Non ADHD spouse and new here. Sad, frustrated.

hi Everyone. I really love my partner.  I am really sad though. He has been on ADHD meds for a year but I am feeling like I still am getting the short end of the stick with the relationship.

It has to get to 'crisis' mode for him to work on his debt load.  I have tried to talk to him, be a partner, encourage him, coach him, etc. To no avail.  I got really upset, and have threatened to end the relationship if he does not get his debts under control.  He makes 3 times the money I do, and has not put the effort into this in 3 years since his debt load accumulated...he's not in more debt but he is doing little or nothing to lower his debt.  He promises and then I see the line of credit statement, and nothing.  I dont like nagging, and I feel bad for getting so angry, but it seems it is the only thing that works.  But will it work? I do not believe his promises anymore.

Yes, I feel like I am burdening most of the responsibility financially in the relationship to keep things on track.

Then there are the unmet commitments.  When we were talking about buying a house together I told him that it was very important to me to be at least engaged first. I do not want to be a 'live in girlfriend'.  He understood and agreed that this was something that would happen.  Here we are 3 + years later after the house purchase and this has not happened.  I told him that it hurts, and that I have stood up to my commitments, but he has not.  I am not going to nag him over this, as I have too much pride to badger a man to marry me.   I have started going to family functions on my own and just doing my own things to meet my needs as I feel awkward over this all. 

I guess I am feeling that I took all the risk, moved away from my home and livelihood, restructured my life to build one with him and have had him not meet his promises.  I feel quite used actually.  I am seriously considering cutting my losses now, ending the relationship and moving on.  I do not want to be in a relationship where I am the 'mother figure'; I want mutuality and someone that wants to plan for the future together.  I have talked to him about it all and asked him if it is possible that maybe I am just not the right person for him, and if that is true, lets figure that out now, as I want him to be happy and not be with me because he is 'supposed' to be.

And yes, he was amazingly charming and attentive at the start of the relationship. 

Thoughts?
