Reached my [HLM] breaking point and need to vent

Months ago (on an account that I then deleted) i made a post regarding my situation. Here is the sum up:

Early 30s, together for 12 years, DB for 3 years but never very active overall.

We were on holiday and before the first night she [LLF] asked me [HLM] to sleep in the other bedroom. One day, after a shower, we were chilling in the same bed and out of the blue she asked me to touch her vagina and masturbate her.

I happily obliged and after i made her orgasm i kept kissing her expecting something in return. When I asked if it was my turn she just said “No”.

That was my breaking point.

When we came back home we had multiple talk and after being gaslighted and being told that she feels oppressed i told her that i didn’t know that i would never try to initiate any kind of physical contact again. After that i told her that i’m missing the intimacy and the flirty attitude we once had while constantly feeling disgusting and rejected and that I would try to make it work but i’m sure i will not be able to hold forever.

I kept my word and i never initiated any kind of physical contact and it’s been about 6 months since our last sexual encounter.

Right now she is facing some challenging changes in her life and i’m going to support her for a few months until she is done but after that i’m going to walk out.

I feel like we are roomates but i’m giving her almost 100% of my free time and i feel trapped. She even told me that i’m developing some important depression issues and i need to talk to someone about that.
