I have a step son who just turned 18. He's been in transition the last 2 years and has been going through HRT for a full year now. He turned 18 and we had a party for him. He told me and my husband a few days ago he's gonna marry his boyfriend and I'm wondering would it make me a bad person to advise against it. My step son has a lot of trauma and abandonment issues because of his mom so he gets attached to people like his boyfriend and I feel he's overlooking some red flags. For starters, his boyfriend let's his friends and family misgender him. Usually if they don't know my step son is trans they use the correct pronouns because he's pretty passing but if they know they misgender him all the time and his boyfriend never corrects them. His boyfriend also has really bad anger issues. He's not abusive but won't get help. He went to one therapy session and said he didn't like it and isn't doing it anymore. I just feel like he needs a lot of help before he can be a good husband. My step son has enough trauma and I think marrying this person especially so young is a bad idea
