Concerned about the stability of a life and future

[cnstx26]

My partner 52M and I F 43 have been together for almost 2 years. As long as I have known him, he has not had a stable career and has a car business along with a website, but it has always been up and down, mostly down lately, and he supplements with side work and gigs. When we met, he gave me the impression he was financially stable and when I had been laid off of my last job, he told me I would never have to worry and he would take care of me. All these plans and even being generous with money within the first year made me feel safe, seen and cared for. I have since been working again though and his financial help backed way off and that's when I noticed his ambition go down and the care and safety I felt from him making sure I was okay and didn't have to worry dwindled. 

He is absolutely brilliant and can do so many things. He is most fluent in computers and knows alot about auto repair, and he has continuously spoken about wanting to open up other businesses and develop a really cool app which I know he is capable of. He also has ADHD and his mind is a powerhouse when used in a positive way. Everytime I think he will move towards something though, he changes his mind after getting me involved, getting excited and then deciding it's not what he wants to pursue anymore.

Most recently, he got very excited about a new mobile mechanic business and we were starting it up. I mean got a web page, name and everything. He then decides it's too much physical labor, especially in the heat. Well he knew that already, but why get me involved and get me excited especially when I could supplement my income with commissions from the jobs. Just a few days later, he wants to change to something else and asks me to help with that. I am already doing my own thing and pursuing my goals and the last thing I need is to waste time on pipe dreams.

I am concerned about his lack of follow through, wasted potential, changing his mind about endeavors one day to the next and because he does not want to work "for the man" yet not pick something and stick with it, I am ultimately concerned about our future and stability.

We are too old to be doing this and he knows and willingly has gone along with the life and future I want but seems to be stuck. He wants to be with me, build a life and get somewhere further but I am not sure how well he is going to help execute these plans. He will have all these grand plans and ideas that don't stick or come to pass.I love him and want to be with him,but starting to have serious doubts. Can I get some guidance please and how I should handle this or what I can do?

Two years is long enough to see who a person truly is.  You now know this about him, that he doesn't have a real career, doesn't hold a job consistently, and is not financially stable.  You can't change him, you can only make your own smart decisions based on this information.  Don't marry him, and don't intermix your finances with his.  Keep your own job and your own finances so he doesn't ruin you financially.
