The thing about BDSM relationships is that context and consent is everything. You can have a very, very hard relationship where consent was only given once, in the beginning, and have no abuse what-so-ever. Or you can have a relationship that, compared to many BDSM relationships, is very light yet full of abuse. Assuming that this is real the information given here is not sufficient to make that judgement.

Donthong, you asked for suggestion but you did not say about what, and that is the critical piece of missing information. What is it that you would like advice on? How to endure this, how to talk to him about it, how to make it stop? Until we know what your looking for we cannot offer any meaningful advice.
