State of resentment

After years of only me (HLF) putting effort to try to improve our sex life, he (LLM) wants to start trying too but I feel resentment towards him.

We started going to couples counciling last month and ever since he has been trying to an effort for us to reconnect but I lothe his touch now. We had sex 3 times since we started couples counseling but I cannot concentrate. I feel disconnected from him.

Has anyone been in a similar situation? I am feeling so much resentment towards him now and it's almost like I look at him as a roommate. I don't understand why my head is not accepting him now. He is clearly trying but I think I am worried of getting hurt again. I do not want to open up to him and let him in (literally and figuratively haha) then find out that this is just a temporary thing and he'll revert back to the way he was...
