I struggled with this when I left my ex. I knew he liked cross dressing, he'd introduced it into our relationship. He would make me do stuff during sex that I felt awkward about, but he said he liked a bit of kink and I went along with it, because that was what he wanted.
When I found trans porn on the computer after he kicked me out of our shared office space, I realised there was something else going on and I was in shock for a few days. I didn't talk to him about it. The clothing he bought for "me for my birthday" was actually 3 sizes too small and for him, but again, I didn't know that.
I asked my marriage therapist about this, because I just feel like I am incapable of making the right decision when it comes to loving men in my life.
For example: I have an ex that I still love, he's still in my life (best friends), but he's histrionic, traumatised by his past and we never worked out because of poor life choices and timing, he reminds me of my ex, but the good stuff. Intelligent, kind, funny, empathetic, but he's moody, prone to making quick decisions based on emotion and not logic and dismissive about other's issues.
My husband on the other hand, steady, consistent, a great father, but not communicative, not demonstrative, logical, calm. He's the complete opposite to my Ex, and to my best friend. The marriage therapist asked me with the benefit of hindsight, would I have chosen my Ex (the trans mtf) again, if I knew then what I know now. I said no. She didn't ask me about my best friend, but I feel if I knew then what I know now, I wouldn't have had a relationship with my best friend. My husband on the other hand, I would absolutely choose again. My therapist said to me, if I wouldn't make the same choices again, then there was nothing wrong with my judgement.
I still sometimes struggle with the head games that ex played. He gaslit me so well that sometimes I was unable to distinguish truth from lies. He told me he liked to dress up as a kid, but was told off by his parents (true), he told me he'd been married before but she died in a car accident (not true), told me he'd been injured in the army (still don't know if that's true). The sexual stuff he made me do, I can barely think about without feeling ill.
In the end, for me to heal, I have to focus on now. What is currently real now. You also need to focus on now and not the past. Everything we have been through, we have survived. The next step is to get therapy/counseling if you haven't started already. That is something I didn't do after I left my ex and I am paying the price for now.
