Husband goes to his mom about EVERYTHING

My husband is a HUGE mamas boy and I honestly don't even mean that in a derogatory sense. He adores his mom and she's a great woman. Me and her get along a lot and she's grateful for me because my husband has been through some traumatic shit. Things she didn't know about until he started writing music about it when he was 16. He went a long time not trusting anyone so she thought he wouldn't have friends or date. So she's just grateful he learned to trust again. My husband talks to his mom on almost a daily basis for at least 10 minutes which I don't mind. One thing is, when my husband has something going on he usually goes to his mom before he goes to me. I know his mom has guilt for not being able to protect him. I also know for a very long time she was the only person he trusted. But as his wife I do want him to come to me when something is wrong. Example I found out he's been having nightmares lately about things from his childhood and they've been stressing him out and he was crying to his mom about not being able to have peace even when he sleeps. He realized in therapy some dates are coming up and maybe that's where the nightmares are coming from. He did eventually talk to me about his feelings but it's always after he talks to his mom. I don't want it to sound like I'm making his trauma about me. However as his wife I would like to be the first he talks to when he's struggling mentally. I'm actually here to help him. I married him. Trauma and all so I want to be his person ya know?
