No. You’re not unreasonable to feel let down.
IME counsellors can be extremely bad at dealing with abuse and can, in fact, allow themselves to become tools of the abuse very easily.
My experience was with a relate counsellor (as chosen by STBXH). In the initial session - the one where they are checking for suitability etc - he totally manipulated the entire process. Played the victim. He even admitted to me afterwards that he was purposefully using the session to ‘prove’ I was in the wrong. He wanted to enlist the counsellor as his weapon against me.
In the individual session, I had with the counsellor we were allocated, I discussed this with her. So she definitely KNEW that he’d told me this was his intention. I also discussed several other things with her, including how he was financially abusing me and I had no access to money even to feed and clothe my children. That he’d purposeful lied and obsfucated to make me think that I was just overspending rather than him controlling all the money.
i was, as you can imagine, as mess. I was on maternity leave, with no access to money (he’d timed this for me not having any income), with obvious postnatal depression (on antidepressants), having recently had an unexpected pregnancy and miscarriage that I hadn’t even been able to tell him about at the time because it was hard enough without him being awful to me about that (he was when he found out). I was angry and all over the place.
Yet this counsellor not only decided to continue with the counselling, but actively took his side against me. In the final session, it turned into her telling me off and lecturing me about his I just had to remove boundaries I’d put in place to protect myself because the lack of them caused me to be depressed to the point of suicide ideation (and I’d told her about this, including that id worked with a counsellor to figure out some boundaries). I asked for the session to stop and she refused to stop. She continued, just telling my husband what he wanted to hear.
I left that night, with police involvement because he was threatening to prevent me leaving with the breastfed baby - and went to my mums with no money at all. I ended up in emergency homeless accommodation because of how awful my STBXH was. That counsellor not only failed to recognise a dangerous situation, but actually colluded with him in making me much less safe.
I later discovered that his account of relate counselling with his first wife, also involved him enlisting the counsellor to his side to the point that she got upset and angry and stormed out. At which point the counsellor apparently talked to him about he’s such a poor victim and so on. Which sounds very similar to what happened to me (except I had to have it happen on zoom in my home with nowhere to escape too).
There are a lot of extremely bad counsellors out there who do a great deal of damage to victims of domestic abuse. Especially if they dare not to present as nice, sympathetic victims. You’d think that could sellers would know that traumatised people don’t present nicely. But no.
My experience was also that relate’s complaints process is as useful as a chocolate teapot. It took many sessions in the domestic abuse counselling the homelessness services social worker referred me to for me to learn to recognise how badly I had been let down. And that it’s not at all uncommon for women to have these kind of experiences, especially with partners who are extremely good at presenting their perplexed, reasonable guy with mental wife image to the world.
