I was told to come here by /r/asktrp:

I've been in an LTR for a year and a half. I won her over by being alpha as fuck. I used to have all the power in the relationship I'm ashamed to admit that I've been acting like a beta-bitch recently by being emotional/clingy, degrading my physical appearance (but this is partially because I'm a workaholic and I enjoy just sitting in a room for 20 hours and getting something productive done), and not asserting myself in the bedroom.

This has lead to her being less interested in me which means now she has the power in the relationship as "the one who has the most power is the one who cares the least"

What can I do in the short-term and long-term to regain the power in my relationship? For those who say "drop the oneitis and start spinning plates", like I said I'm a workaholic and I put my career first, so I would rather mend this LTR because I don't have the time to invest in new relationships.
